i'm not saying conv plasma really kills people but when it's associated with 3x higher mortality in a randomized trial i feel like that should be mentioned in the abstract rather than just saying "no significant reduction in mortality was observed"
Tiny randomized trial of convalescent plasma for people with severe Covid-19 (only 29): despite some early signs of benefit, no significant reduction in hospitalization or mortality, & not significantly less likely to progress to needing ventilation
