A retraction notice was published regarding the study titled: “Cardiovascular disease, drug therapy, and mortality in COVID-19,” which appeared in The New England Journal of Medicine on May 1st. 

• Because of concerns that arose from a separate study concerning data from Surgisphere, the authors launched an independent third-party peer review of the full data set
• Surgisphere refused to transfer the full data set, leading to their withdrawal of the paper
• The authors also used Surgisphere for a data set published in The Lancet, which is also being retracted
