Is 5.6% vs 2.7% really a 51% increase, or just a 2.9% increase? I admit that the former looks better, but I consider it misleading. Considering that the outcomes were just reports about how the patients felt, and how they seemed to be playing some complex statistical games (deciding what groupings and levels to assign to which outcome), I'm not convinced that this is a significant treatment rather than just a "adjust things to make the study look good" type of study.
It certainly doesn't make me demand this treatment if I got Covid.
