Surgisphere: mass audit of papers linked to firm behind hydroxychloroquine Lancet study scandal

Questions continue for Surgisphere and CEO Sapan Desai as universities deny knowledge of links to firm behind Lancet's now-disputed blockbuster study

Dozens of scientific papers co-authored by the chief executive of the US tech company behind the Lancet hydroxychloroquine study scandal are now being audited, including one that a scientific integrity expert claims contains images that appear to have been digitally manipulated.

The audit follows a Guardian investigation that found the company, Surgisphere, used suspect data in major scientific studies that were published and then retracted by world-leading medical journals, including the Lancet and the New England Journal of Medicine.
