UK-led clinical trial RECOVERY shows steroid dexamethasone reduces deaths among patients with severe COVID-19

Total of 2104 patients received dexamethasone 6 mg daily. Dexamethasone reduced deaths by one-third in ventilated patients (rate ratio 0.65 [95% CI 0.48 to 0.88]; p=0.0003) and by one fifth in other patients receiving oxygen only (0.80 [0.67 to 0.96]; p=0.0021).
