FDA OKs use of convalescent plasma for COVID-19 | CIDRAP – (caving to pressure for President’s hoed for political gain)

Hahn’s interpretation of the 35% reduction in mortality was widely disputed by scientists on Twitter, who used the same data from the Mayo Clinic to show that 3.2 people out of 100—not 35—would be saved by the administration of convalescent plasma. The difference is in relative versus absolute risk, with 35% being the percent improvement but, because the rate of those seeing improvement was so low—8.7% to 11.9%—the absolute reduction is much smaller.

Also, even for that small absolute improvement, the plasma would need to be administered within 3 days versus 7, according to the Mayo data. (problem – who gets test results back within 3 days?)
