COVID-19 Update 80 with Roger Seheult, MD of https://www.medcram.com who discusses the recent retractions from well-established peer-reviewed journals The Lancet and New England Journal of Medicine.
The retracted COVID 19 studies primarily focused on the efficacy and associated mortality of the medications hydroxychloroquine, azithromycin, ace-inhibitors, and angiotensin receptor blockers, and relied on data from a small company called Surgisphere. The Guardian first reported about and error in the Surgisphere data set which has served to undermine the validity of these studies for many including most of the authors of the studies themselves (This video was recorded June 5, 2020).
