This study reveals the disparities in open data sharing policies among medical journals, with only a third allowing manuscript deposit and reuse, and around half agreeing to publish documents online and include supplementary material. However, only 9.5% of articles analyzed contained supplementary material, with main journals like BMJ Open, JAMA Network Open, New England Journal of Medicine, Lancet and Plos Medicine leading the way.
Background As part of the Open Science movement, this study aims to analyze the current state of open access and open data policies concerning the availability of articles and raw data of the journals belonging to the category Medicine, General & Internal of the Science Citation Index Expanded. Methods Journal data sharing policies were evaluated through the following variables: possibility of manuscript storage in repositories; reuse policy; publication on a website; and statement regarding complementary material. Subsequently, an analysis of the supplementary material associated with each article was performed through the PubMed Central repository. The study reported was assessed following the STROBE guidelines for observational studies. Results This study shows that only one-third of the journals included in the category Medicine, General & Internal allow the depositing of their documents in repositories and its reuse, while approximately half of the journals agree to publish the document on a website as well as to deposit supplementary material along with the publication. However, the reality about this last variable is that only 9.5% of the articles analyzed contained supplementary material being the main journals involved, BMJ Open, JAMA Network Open, New England Journal of Medicine, Lancet and Plos Medicine. Conclusions The analysis of the opening policies of the journals concerning data availability in medical research reveals the unequal positioning of publishers towards the sharing of open data, the ambiguity regarding government policies about the obligation to deposit data and the need for ethical and standardization requirements in the typology/format of the data deposited without forgetting the important role that the researcher plays. Further studies based on journals indexed in medical databases other than Science Citation Index Expanded are needed.
