Preprints vs. Journal Articles: Citation Impact in COVID-19 Research

Focusing on article and citation count, this study examined 110 academic journals whose papers on COVID-19 were indexed in PubMed from 2020 to 2023. To analyze these journals characteristics, this study introduced the concepts of paper ratio, citation ratio, and citation impact. Journals with similar trends in paper and citation count were positioned near the diagonal on a two-dimensional graph (y=x) with paper ratio on the x-axis and citation ratio on the y-axis, indicating a slope close to 1. Conversely, the greater the disparity between paper ratio and citation ratio, the wider the angle between the journals position and the diagonal. Of the 110 journals in 2020, 83 were above the diagonal with a citation impact greater than 1, while 27 were below the diagonal with a citation impact of 1 or lower. Notably, nine journals--BMC Health Services Research, Genome Medicine, Nature, Annals of Epidemiology, BMC Bioinformatics, Nature Microbiology, PLoS Computational Biology, Medicine (Baltimore), and Journal of Clinical Investigation--showed high citation impact, with preprint-distributed papers being cited nearly five times more than directly submitted papers. This study demonstrates that articles initially distributed as preprints in these journals tend to receive substantially more citations than directly submitted ones.

The Impact of Preprints on the Citations of Journal Articles Related to COVID-19

To investigate the impact of preprints on the citation counts of COVID-19-related papers, this study compares the number of citations received by drafts initially distributed as preprints and later published in journals with those received by papers directly submitted to journals. The difference in the median number of citations between COVID-19 preprint-distributed papers and COVID-19 directly submitted papers published in 184 journals was tested using the Mann-Whitney U test. The results showed that 129 journals had a statistically significant higher median citation count for COVID-19 preprint-distributed papers compared to directly submitted papers, with a p-value of less than 0.05. In contrast, no journals had a statistically significant higher median citation count for COVID-19 directly submitted papers. This indicates that 70.11% of the journals that published preprint-distributed papers experienced a significant increase in citations. We also identified that among the 184 journals, 13 journals garnered a substantial number of citations. Among the 74,037 COVID-19 papers, preprint-distributed papers (9,028) accounted for only 12.19%. However, among the 2,015,997 citations received by COVID-19 papers, preprint-distributed papers garnered 542,715 citations, representing a substantial 26.92%. These results suggest that distributing preprints prior to formal publication may help COVID-19 research reach a wider audience, potentially leading to increased readership and citations.

The Impact of Preprints on COVID-19 Research Dissemination: A Quantitative Analysis of Journal Publications

Preprints have played an unprecedented role in disseminating COVID-19-related science results to the public. The study aims to elucidate the role of preprints during the COVID-19 public health emergency (2020-2023) through a quantitative analysis of journal papers. Among the 247,854 COVID-19-related papers published in PubMed, 12,152 were initially released as preprints and were eventually published in 1,380 journals. This number is more than five times the 246 journals to which submissions can be made directly from bioRxiv through the B2J program. Journals with higher impact factors and Normalized Eigenfactor scores tend to publish a larger number of preprint-derived articles. The proportion of preprints among PubMed papers was 0.049, but this varies significantly by journal. In the top 30 journals, most exceed this proportion, indicating that these journals are preferred by authors for submitting their work. These findings highlight the growing acceptance and impact of preprints in the scientific community, particularly in high-impact journals.
