Uncertainty abounds - even as we get better data on treatments, with the big RCTs beginning to report, and new trials on masks, the evidence remains uncertain, in both the statistical realm (confidence intervals crossing 0) and in what to do in the face of that continuing lack of clear effect. As always Helen Macdonald and Duncan Jarvies are looking at the evidence, and this week are joined by John Brodersen, professor of general practice at the University of Copenhagen. Helen talks to Bram Rochwerg, methodology lead on the WHO treatment guidelines for covid, about why their latest review has stopped recommending remdesivir for covid-19 treatment.
