RECOVERY dexamethasone
  NCT04381936		 RCTdexamethasonestandard of careCOVID 19 hospitalizedsome concern
2104/4321 conclusif
  • demonstrated 17 % decrease in deaths (PE) with a moderate degree of certainty due to some concern in risk of bias
  • suggested 10 % increase in hospital discharge with a moderate degree of certainty due to some concern in risk of bias
  • suggested 23 % decrease in mechanical ventilation with a moderate degree of certainty due to some concern in risk of bias
in an exploratory subgroup analysis there was no benefit among patients who did not require oxygen (1.22 [0.86 to 1.75]; p=0.14)
