A comparison of scientometric data and publication policies of ophthalmology journals

Abstract: Purpose: 

This retrospective database analysis study aims to present the scientometric data of journals publishing in the field of ophthalmology and to compare the scientometric data of ophthalmology journals according to the open access (OA) publishing policies.


The scientometric data of 48 journals were obtained from Clarivate Analytics InCites and Scimago Journal & Country Rank websites. Journal impact factor (JIF), Eigenfactor score (ES), scientific journal ranking (SJR), and Hirsch index (HI) were included. The OA publishing policies were separated into full OA with publishing fees, full OA without fees, and hybrid OA. The fees were stated as US dollars (USD).


Four scientometric indexes had strong positive correlations; the highest correlation coefficients were observed between the SJR and JIF (R = 0.906) and the SJR and HI (R = 0.798). However, journals in the first quartile according to JIF were in the second and third quartiles according to the SJR and HI and in the fourth quartile in the ES. The OA articles published in hybrid journals received a median of 1.17-fold (0.15–2.71) more citations. Only HI was higher in hybrid OA; other scientometric indexes were similar with full OA journals. Full OA journals charged a median of 1525 USD lower than hybrid journals.


Full OA model in ophthalmology journals does not have a positive effect on the scientometric indexes. In hybrid OA journals, choosing to publish OA may increase citations, but it would be more accurate to evaluate this on a journal basis.

What are the benefits of open access? TIB study confirms advantages and dispels reservations – Technische Informationsbibliothek (TIB)

“Open access – free access to scholarly publications – offers many advantages. As surveys show, however, some researchers still have reservations. In the past decade, numerous empirical studies have been published providing substantiated results on the hopes and concerns regarding open access….

To conduct this review, TIB identified a total of 318 scientific studies that empirically examine various effects of open access. From this corpus, the authors selected 61 particularly relevant studies for a systematic comparison; these were then analysed thoroughly and the various results were compared in detail.

The effects studied relate to seven major aspects of open access:

Attention in the scientific community
Quality of scientific publications
Knowledge transfer
Productivity of the publishing system
Use of publications
Inequality in the science system
Economic impact on the publishing system…

Dr. David Hopf, lead author of the study, reported the key findings: “The literature reviewed confirms several advantages of open access: open access leads to increased usage and to a professionally and geographically more diverse readership. At the same time, open access publications make a greater contribution to knowledge transfer than traditionally published research results, and the publishing process – the time between the submission and acceptance or publication of articles – is shorter. What is more, a number of negative concerns assumed in relation to the effects of open access – for example, that open access publications are of an inferior quality and lead to disadvantages in print edition sales – have been dispelled.”

However, one partial result came as a surprise: the fact that open access publications are cited more frequently than publications that are not freely available is often mentioned as an advantage of open access – and is also confirmed by most empirical studies. However, a substantial proportion of the empirical literature deviates from this result, which means that an OA citation advantage cannot be conclusively confirmed empirically. In light of a high level of plausibility and methodological difficulties in this area, however, it can still be assumed that such an advantage exists.

Just one finding indicates a negative effect of open access: where so-called article processing charges (APCs) – publication costs incurred by many open access publications – exist, authors with fewer resources may be discouraged from publishing open access, e.g. due to low income levels in some regions of the world or a lack of institutional funding. However, this is not an effect of open access per se, but rather an effect of a particular business model for financing open access publications….”

Correlation Between Altmetric Attention Scores and Citations for Articles Published in High–Impact Factor Ophthalmology Journals From 2018 to 2019 | Medical Journals and Publishing | JAMA Ophthalmology | JAMA Network

Importance  The Altmetric attention score (AAS) provides new information to gauge the impact of a research article not found through typical metrics, such as impact factor or citation counts. Objective  To explore the association between AAS and common impact markers among high-impact ophthalmology journals from 2018 to 2019. Design, Setting, and Participants  All articles published in the American Journal of Ophthalmology (AJO), JAMA Ophthalmology (JAMAO), and Ophthalmology (OPH) from January 1, 2018, to December 31, 2019, were collected for this cross-sectional study. Excluded articles were those missing Altmetric data at the time of data collection. The AAS and associated social media impact for each article were collected with the AAS calculator bookmarklet. Spearman rank correlation analyses and analysis of variance tests were conducted to assess differences in various metrics between AJO, JAMAO, and OPH. The study included articles published of all document types (article, conference paper, editorial, erratum, letter, note, retracted, review, and short survey) and access status (open access and not open access). Main Outcomes and Measures  The correlation between citation counts and Altmetric variables including AAS. Results  A total of 2467 articles were published in the study period. There were 351 articles excluded owing to missing Altmetric data. Of the 2116 articles included in the analysis, 1039 (49.1%) were published in 2018, and 1077 (50.9%) were published in 2019; the mean number of citations was 8.8 (95% CI, 7.9-9.6) for AJO, 6.2 (95% CI, 5.3-7.1) for JAMAO, and 15.1 (95% CI, 13.3-17.0) for OPH. The mean AAS was 4.5 (95% CI, 3.3-5.6) for AJO (723 publications), 27.4 (95% CI, 22.1-32.8) for JAMAO (758 publications), and 15.1 (95% CI, 10.9-19.3) for OPH (635 publications). Citation rate was moderately correlated with AAS across the 3 journals (AJO, ??=?0.39; P?<?.001; JAMAO, ??=?0.41; P?<?.001; OPH, ??=?0.40; P?<?.001), as well as minimally or moderately correlated with engagement or mention by Facebook posts (AJO, ??=?0.38; P?<?.001; JAMAO, ??=?0.24; P?<?.001; OPH, ??=?0.20; P?<?.001), news outlet reporting (AJO, ??=?0.12; P?<?.001; JAMAO, ??=?0.38; P?<?.001; OPH, ??=?0.19; P?<?.001), and Twitter posts (AJO, ??=?0.40; P?<?.001; JAMAO, ??=?0.38; P?<?.001; OPH, ??=?0.42; P?<?.001). Conclusions and Relevance  Results of this cross-sectional study suggest that citation rate has a moderate positive correlation with online and social media sharing of research in ophthalmology literature. Peer-reviewed journals may increase their reach and impact by sharing their literature through social media and online platforms.

The Price of Publishing: An Investigation of the Open Access… : Plastic and Reconstructive Surgery

Abstract:  Background: 

Open access publishing in plastic surgery has rapidly gained traction in the past decade. This study investigated the digital landscape of plastic surgery open access publishing.


This was a cross-sectional bibliometric investigation of plastic surgery–focused journals. Three publication models were investigated: subscription-only journals, hybrid journals offering both paywalled and open access publishing, and open access–only journals.


Eighty-two journals were investigated. In 2010, open access journals comprised 18 percent of all plastic surgery journals online, subscription journals comprised 79 percent, and hybrid journals comprised 3 percent. Conversely, in 2020, open access journals comprised 55 percent of all journals, hybrid journals comprised 45 percent, and there were no subscription-only journals. Multivariable linear regression adjusting for article type/content demonstrated that open access articles from hybrid journals [beta coefficient, 1.3; F(4, 18) = 790; p = 0.05] and high-quality open access journals [beta coefficient, 0.9; F(4, 19) = 738; p = 0.04] were significantly positively associated with number of full-text views. Although impact factor and article processing charges were positively correlated [Pearson correlation coefficient: r(25) = 0.39, p = 0.04] for open access publishing, some high-quality open access journals were found to offer fee waivers/free publishing. Lastly, level of evidence offered by articles from open access versus hybrid journals differed.


Overall, this study highlighted important distinctions between trustworthy and predatory journals offering open access publishing in plastic surgery. Open access publishing in trustworthy sources offers greater visibility and is not necessarily cost-prohibitive, but some open access journals can be limited in scope (i.e., less coverage of subspecialty topics) and quality of content. Study findings were used to generate recommendations for navigating open access publishing in plastic surgery.

Article Processing Charges, Altmetrics and Citation Impact: Is there an economic rationale?

Abstract:  The present study aims to analyze 1) the relationship between Citation Normalized Score of scientific publications and Article Processing Charges (APCs) of Gold Open Access (OA) publications 2) the determinants of APCs. To do so, we used APCs information provided by the OpenAPC database, citation scores of publications from the WoS database and, for Altmetrics, data from this http URL database, over the period from 2006 to 2019 for 83,752 articles published in 4751 journals belonging to 267 distinct publishers. Results show that contrary to common belief, paying high APCs does not necessarily increase the impact of publications. First, large publishers with high impact are not the most expensive. Second, publishers with the highest APCs are not necessarily the best in terms of impact. Correlation between APCs and impact is moderate. Regarding the determinants, results indicate that APCs are on average 50% higher in hybrid journals than in full OA journals. The results also suggest that Altmetrics do not have a great impact: OA articles that have garnered the most attention on internet are articles with relatively low APCs. Another interesting result is that the “number of readers” indicator is more effective as it is more correlated with classic bibliometrics indicators than the Altmetrics score.


The Rise of Open Access Journals in Radiation Oncology: Are We Paying for Impact? – ScienceDirect


We aimed to examine how the rise of open access (OA) journals in biomedicine has impacted resident research in radiation oncology.


We built a comprehensive database of first-author, PubMed-searchable articles published by US radiation oncology residents who graduated between 2015 and 2019. We then classified each journal in which these manuscripts appeared as either OA or non-OA, and obtained the current article processing charge (APC) for every publication that appeared in an OA journal. Lastly, we performed a secondary analysis to identify the factors associated with publishing an article in an OA journal.


The US radiation oncology residents in this study published 2,637 first-author, PubMed-searchable manuscripts, 555 (21.0%) of which appeared in 138 OA journals. The number of publications in OA journals increased from 0.47 per resident for the class of 2015 to 0.79 per resident for the class of 2019. Likewise, the number of publications in OA journals with a 2019 impact factor of zero increased from 0.14 per resident for the class of 2015 to 0.43 per resident for the class of 2019. Publications in OA journals garnered fewer citations than those in non-OA journals (8.9 versus 14.9, P < 0.01). 90.6% of OA journals levy an APC for original research reports (median $1,896), which is positively correlated with their 2019 impact factor (r?=?0.63, P < 0.01). Aggregate APCs totaled $900,319.21 for all US radiation oncology residency programs and appeared to increase over the study period.


The number of first-author, PubMed-searchable manuscripts published by graduating US radiation oncology residents in OA journals rose significantly over the study period. US radiation oncology residency programs appear to be investing increasing and significant sums of money to publish the work of their residents in these journals. A more substantive discussion about the proper role of OA journals in resident research is needed.

The long-term influence of Open Access on the scientific and social impact of dental journal articles: An updated analysis – ScienceDirect

Abstract:  Objectives

To investigate whether dental journal articles that are Open Access (OA) receive greater citation counts and higher Altmetric Attention Scores (AAS) than articles that are non-OA in the long term.


Eligible dental journal articles published in 2013 were identified via PubMed, and Web of science, Unpaywall and corresponding URLs were manually checked to determine the OA status of each included article 7 years after publication. Citation counts were extracted from Web of Science and Scopus, and AAS was harvested from the Altmetric Explorer. Multivariable general linear regression analyses were performed to investigate the association between OA and citation count, as well as between OA and AAS.


Among the 755 included articles, 309 (40.9%) were freely available online. Among the 309 OA articles, articles available from publishers accounted for 64.4% (199/309) of all OA articles, and those available through self-archiving accounted for 56.0% (173/309). According to regression analyses, OA articles had significantly greater citation counts (P = 0.001) and AAS (P < 0.001) than non-OA articles.

Conclusions/clinical significance

In the field of dentistry, about 41% of journal articles are OA 7 years after publication, and OA articles available from the publishers are more common than those from authors through self-archiving. OA articles tend to have greater scientific and social impact than non-OA articles in the long term.

Analyzing Faculty Open Access Publishing: A citation analysis of select colleges at the University of South Florida – ScienceDirect

Abstract:  In scholarly communication literature, an Open Access citation advantage refers to articles published or released as Open Access receiving a higher citation count than articles that are not released Open Access. This article considers Open Access citation advantage factors at the University of South Florida. Data from Scopus and Open Access Button was used to examine publication activity from a five-year range in seven different departments. The data indicated that an Open Access citation advantage does exist in most of those departments. Future research is necessary to look at other departments.


Publication cultures and the citation impact of open access – Eger – 2021 – Managerial and Decision Economics – Wiley Online Library

Does open access (OA) to journal articles foster citations to these articles? We compare the citation impact of gold and green OA in two disciplines: Biology and Economics & Management. The empirical analysis covers all articles of these disciplines included in the Web of Science “Journal Citation Reports” between 2000 and 2019. We show that, controlling for confounding variables pertaining to the journals and articles, gold OA increases citations across all articles. However, the individual disciplines feature starkly different effects: a 18.3% increase in Biology, compared to a decrease by 30.9% in Economics & Management. Also Green OA leads to an increase in citations to academic research. These results are confirmed by a number of robustness checks.

Contribution of the Open Access Modality to the Impact of Hybrid Journals Controlling by Field and Time Effects

Researchers are more likely to read and cite papers to which they have access than those that they cannot obtain. Thus, the objective of this work is to analyze the contribution of the Open Access (OA) modality to the impact of hybrid journals. For this, the research articles in the year 2017 from 200 hybrid journals in four subject areas, and the citations received by such articles in the period 2017-2020 in the Scopus database, were analyzed. The journals were randomly selected from those with share of OA papers higher than some minimal value. More than 60 thousand research articles were analyzed in the sample, of which 24% under the OA modality. As results, we obtain that cites per article in both hybrid modalities strongly correlate. However, there is no correlation between the OA prevalence and cites per article in any of the hybrid modalities. There is OA citation advantage in 80% of hybrid journals. Moreover, the OA citation advantage is consistent across fields and held in time. We obtain an OA citation advantage of 50% in average, and higher than 37% in half of the hybrid journals. Finally, the OA citation advantage is higher in Humanities than in Science and Social Science.

Citation Advantage of Promoted Articles in a Cross-Publisher Distribution Platform: 36-Month Follow-up to a Randomized Controlled Trial

Abstract:  Background:

There are limited evidence-based strategies that have been shown to increase the rate at which peer-reviewed articles are cited. In a previously reported randomized controlled trial, we demonstrated that promotion of article links in an online cross-publisher distribution platform (TrendMD) persistently augments citation rates after 12 months, leading to a statistically significant 50% increase in citations relative to the control.

Objective:This study aims to investigate if the citation advantage of promoted articles upholds after 36 months.

Methods:A total of 3200 published articles in 64 peer-reviewed journals across 8 subject areas were block randomized at the subject level to either the TrendMD group (n=1600) or the control group (n=1600) of the study. Articles were promoted in the TrendMD Network for 6 months. We compared the citation rates in both groups after 36 months.

Results:At 36 months, we found the citation advantage endured; articles randomized to TrendMD showed a 28% increase in mean citations relative to the control. The difference in mean citations at 36 months for articles randomized to TrendMD versus the control was 10.52 (95% CI 3.79-17.25) and was statistically significant (P=.001).

Conclusions:To our knowledge, this is the first randomized controlled trial to demonstrate how a postpublication article promotion intervention can be used to persistently augment citations of peer-reviewed articles. TrendMD is an efficient digital tool for knowledge translation and dissemination to targeted audiences to facilitate the uptake of research.

More readers in more places: the benefits of open access for scholarly books

Abstract:  Open access to scholarly contents has grown substantially in recent years. This includes the number of books published open access online. However, there is limited study on how usage patterns (via downloads, citations and web visibility) of these books may differ from their closed counterparts. Such information is not only important for book publishers, but also for researchers in disciplines where books are the norm. This article reports on findings from comparing samples of books published by Springer Nature to shed light on differences in usage patterns across open access and closed books. The study includes a selection of 281 open access books and a sample of 3,653 closed books (drawn from 21,059 closed books using stratified random sampling). The books are stratified by combinations of book type, discipline and year of publication to enable likewise comparisons within each stratum and to maximize statistical power of the sample. The results show higher geographic diversity of usage, higher numbers of downloads and more citations for open access books across all strata. Importantly, open access books have increased access and usage for traditionally underserved populations.


Going for Gold: How does the access type of articles in hybrid journals affect the reach and impact of research?

“Many studies have already looked at the advantages of publishing open access (OA) over non-OA, however few have explored the effects of publishing OA articles in hybrid journals—journals that contain both a mixture of OA and non-OA articles. Fewer still have directly compared the differences in impact and reach for the full range of publishing models in hybrid journals, such as Gold OA articles to subscription articles where an earlier article version (e.g. the accepted manuscript or preprint) has been self-archived in an OA repository.

In 2021, Springer Nature commissioned an analysis of 60,567 articles published in 1,262 of its hybrid journals, measuring reach by the number of downloads and the attention reflected in the Altmetric Attention Score, and impact through the number of citations. This presentation will discuss the findings from the recent Springer Nature white paper, “Going for Gold: Exploring the Reach and Impact of Gold Open Access Articles in Hybrid Journals,” as well as potential implications of these findings for authors, and for institutional and funder policy decisions. Jessica Monaghan, Director of Policy and Performance, OA, at Springer Nature will give a presentation and answer your questions.”
