Retraction: Hydroxychloroquine or chloroquine with or without a macrolide for treatment of COVID-19: a multinational registry analysis

Due to this unfortunate development, the authors request that the paper be retracted.

The retraction notice is signed by three of the four authors. It states that the authors launched an independent third-party peer review of the data vendor, that the vendor would not transfer the full dataset, that the reviewers withdrew, and that the authors request retraction. The decision recorded in the notice is the authors' request; the notice does not describe a separate editorial decision.
