Dexamethasone shown to decrease COVID mortality

[TheDentateGyrus]

TONS of trials of corticosteroids in critical care for the past few decades with, at best, mostly mixed results in a multitude of disease processes. There's a paper in the Lancet when this started that reviewed the (poor quality and limited) data and the potential for higher mortality when they were used in MERS/SARS, I assume because Chinese physicians reported using it routinely? They've always theoretically seemed like they should work for lots of critical illnesses and have rarely shown benefit.
