Aims:We aimed at developing a structured study protocol utilizing the bibliographic web-application science performance evaluation (SciPE) to perform comprehensive scientometric analyses.Methods and results: Metadata related to publications derived from online databases were processed and visualized by transferring the information to an undirected multipartite graph and distinct partitioned sets of nodes. Also, institutionspecific data was normalized and merged allowing precise geocoordinate positioning, to enable heatmapping and valid identification. As a result, verified, processed data regarding articles, institutions, journals, authors gender, nations and subject categories can be obtained. We recommend including the total number of publications, citations, the population, research institutions, gross domestic product, and the country-specific modified Hirsch-Index and to form corresponding ratios (e.g. population/publication). Also, our approach includes implementation of bioinformatical methods such as heatmapping based on exact geocoordinates, simple chord diagrams, and the central implementation of specific ratios with plain visualization techniques. Conclusion:This protocol allows precise conduction of contemporaneous scientometric analyses based on bioinformatic and meta-analytical techniques allowing to evaluate and contextualize scientific efforts. Data presentation with the depicted visualization techniques are mandatory for transparent and consistent analyses of research output across different nations and topics. Research performance can then be discussed in a synopsis of all findings.

Background We sought to investigate sex‐specific differences in authorship of cardiovascular research over the past decade. Methods and Results All 387 463 cardiovascular publications between 2010 and 2019 were retrieved from Web of Science. Articles increased from 19 960 to 29 604 articles per year ( P >0.001). The number of articles written by female first authors increased by 76.3% (6434–11 343 articles) and by 35.0% for male first authors (13 526–18 261) ( P <0.001). The first author was more likely to be a female author in articles with female last authors. The median impact factor (IF) for articles by female first authors was lower (2.46 [interquartile range, 7 1.11–4.03] versus 2.51 [interquartile range, 1.17–4.10]; P <0.001). Female authorship articles reached the highest IF in North America (average IF, 3.7), with the lowest in Africa (average IF, 1.8). Conclusions Publications in cardiovascular research have increased over the past decade, particularly by female authors. Female researchers are cited less often compared with their male peers. The IF remains lower for articles by female researchers.

Background Women are underrepresented in cardiovascular publications. We sought to investigate sex-specific differences in cardiovascular research over the last decade. Methods and results All 387,463 cardiovascular publications between 2010–2019 were retrieved from Web-of-Science and analyzed regarding the authors' sex, the average impact factor (IF), the number of citations, co-authors per article, and international collaborations. The number of cardiovascular research articles increased between 2010–2019 from 19,960 to 29,604 articles per year. The number of articles written by female first authors increased by 48.3% (6434 articles in 2010 and 11,343 articles in 2019) and by 35.0% for male first authors (13,526 articles in 2010 and 18,261 articles in 2019). The last/senior author was more likely to be female in articles with female first authors compared with male first authors (28.2% vs. 14.1%; odds ratio 2.48, 95% confidence interval 2.43–2.53, p&lt;0.001). The average IF for articles by female first authors was lower compared to male (3.1±3.8 vs. 3.5±4.9, p&lt;0.001). Likewise, the H-Index was lower for female than male first authors (1.07±0.74 vs. 1.25±0.98, p&lt;0.001), as was the number of citations per articles (14.0±31.1 vs. 18.0±68.8 citations, p&lt;0.001). Female first authors had fewer co-authors per article than their male peers (7.4±19.6 vs. 8.2±35.2; p&lt;0.001) and were less represented in articles with &gt;15 co-authors (3,623 articles by female and 8,941 by male first authors; ratio female to male 0.41). Scientific advancement as the ratio between female to male first authorships was highest in publications from Latin America (ratio 0.92) and lowest in Asia (ratio 0.40). Female authorship articles reached the highest IF in North America (average IF 3.7), the lowest Africa (average IF 1.8). Conclusions Publications in cardiovascular research have increased over the last decade, particularly by female authors. Female researchers are cited less often compared with their male peers and publish with fewer co-authors. The IF remains lower for articles by female researchers.
