Question

What is the concordance among sample size, primary end points, results for primary end points, and interpretations described in preprints of clinical studies posted on medRxiv that are subsequently published in peer-reviewed journals (preprint-journal article pairs)?

Findings

In this cross-sectional study of 547 clinical studies that were initially posted to medRxiv and later published in peer-reviewed journals, 86.4% of preprint-journal article pairs were concordant in terms of sample size, 97.6% in terms of primary end points, 81.1% in terms of results of primary end points, and 96.2% in terms of study interpretations.

Meaning

This study suggests that most clinical studies posted as preprints on medRxiv and subsequently published in peer-reviewed journals had concordant study characteristics, results, and final interpretations.

Objective

To estimate the financial costs paid by individual medical researchers from meeting the article processing charges (APCs) levied by open access journals in 2019.

Design

Cross-sectional analysis.

Data sources

Scopus was used to generate two random samples of researchers, the first with a senior author article indexed in the ‘Medicine’ subject area (general researchers) and the second with an article published in the ten highest-impact factor general clinical medicine journals (high-impact researchers) in 2019.

For each researcher, Scopus was used to identify all first and senior author original research or review articles published in 2019. Data were obtained from Scopus, institutional profiles, Journal Citation Reports, publisher databases, the Directory of Open Access Journals, and individual journal websites.

Main outcome measures

Median APCs paid by general and high-impact researchers for all first and senior author research and review articles published in 2019.

Results

There were 241 general and 246 high-impact researchers identified as eligible for our study. In 2019, the general and high-impact researchers published a total of 914 (median 2, IQR 1–5) and 1471 (4, 2–8) first or senior author research or review articles, respectively. 42% (384/914) of the articles from the general researchers and 29% (428/1471) of the articles from the high-impact medical researchers were published in fully open access journals.

The median total APCs paid by general researchers in 2019 was US$191 (US$0–US$2500) and the median total paid by high-impact researchers was US$2900 (US$0–US$5465); the maximum paid by a single researcher in total APCs was US$30115 and US$34676, respectively.

Conclusions

Medical researchers in 2019 were found to have paid between US$0 and US$34676 in total APCs. As journals with APCs become more common, it is important to continue to evaluate the potential cost to researchers, especially on individuals who may not have the funding or institutional resources to cover these costs.
