Many cardiovascular disease (CVD) journals request data sharing statements upon trial report submission, but their compliance in publishing these statements remains unclear. Therefore it was performed a quantitative analysis to evaluate the current practice of the publications of data sharing statements in clinical trials by CVD journals, which included 78 CVD journals that published clinical trials from Jan 2019 to Dec 2022 and had data sharing statement request.

Among the CVD journals declaring to request data sharing statements upon trial report submission from journal submission instructions, over 30% (24/78) indeed did not publish any statement in their published trial reports. The most frequent obstacle/difficulty in publishing statements, as mentioned by the participated editors-in-chief, was that the published statements may be incongruent with trial authors’ willingness to share data.
