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

Mandeep R Mehra, Frank Ruschitzka, Amit N Patel

After publication of our Lancet Article,1 several concerns were raised with respect to the veracity of the data and analyses conducted by Surgisphere Corporation and its founder and our co-author, Sapan Desai, in our publication. We launched an independent third-party peer review of Surgisphere with the consent of Sapan Desai to evaluate the origination of the database elements, to confirm the completeness of the database, and to replicate the analyses presented in the paper.

Our independent peer reviewers informed us that Surgisphere would not transfer the full dataset, client contracts, and the full ISO audit report to their servers for analysis as such transfer would violate client agreements and confidentiality requirements. As such, our reviewers were not able to conduct an independent and private peer review and therefore notified us of their withdrawal from the peer-review process.

We always aspire to perform our research in accordance with the highest ethical and professional guidelines. We can never forget the responsibility we have as researchers to scrupulously ensure that we rely on data sources that adhere to our high standards. Based on this development, we can no longer vouch for the veracity of the primary data sources.

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

We all entered this collaboration to contribute in good faith and at a time of great need during the COVID-19 pandemic. We deeply apologise to you, the editors, and the journal readership for any embarrassment or inconvenience that this may have caused.

Didier Raoult: Rücknahme des von drei der vier Autoren angeforderten Lancet-Artikels: meine Reaktion: *Panzerknackerbande.*

In einem langen Interview watscht er mehrmals Ruth Elkrief und Margaux de Frouville (*Broumbroumville*, Leserkommentar) ab (*Halten Sie die Klappe!*), wie das kein Deutscher wagen würde. Die beiden hätten von der Sache keine Ahnung, stellten Fragen stellten, in denen die erwartete Antwort schon enthalten sei und darauf werde er nicht eingehen.

Ganz am Ende zu Froufrouville gerichtet: *Sie sehen, das Untier ist nicht so schrecklich und auch nicht so leicht zu manipulieren.*
