A recent randomized trial tested to see whether dexamethasone (a steroid treatment) is useful for folks hospitalized with COVID. They found that it reduced deaths by 33% in ventilated patients and by 20% in patients receiving oxygen only.  There was no benefit among those patients who did not require respiratory support.

Here’s the media release that describes the findings.  The results haven’t yet been published in a peer reviewed journal, so beware, these are just preliminary results and not peer reviewed.
