Very late stage (9 days from symptom onset) RCT with 116 favipiravir patients and 120 arbidol patients in China, showing no significant difference in clinical recovery (relief of fever and cough, respiratory frequency ≤24 times/min, and oxygen saturation ≥98%), however the time to resolution of fever and cough was significantly lower with favipiravir. ChiCTR2000030254.
risk of ICU admission, 3.4% higher, RR 1.03, p = 1.00, treatment 2 of 116 (1.7%), control 2 of 120 (1.7%).
risk of respiratory failure, 74.1% lower, RR 0.26, p = 0.37, treatment 1 of 116 (0.9%), control 4 of 120 (3.3%), NNT 40.
risk of oxygen therapy, 19.5% lower, RR 0.80, p = 0.42, treatment 21 of 116 (18.1%), control 27 of 120 (22.5%), NNT 23.
risk of progression to dyspnea, 70.4% lower, RR 0.30, p = 0.03, treatment 4 of 116 (3.4%), control 14 of 120 (11.7%), NNT 12.
risk of dyspnea, 10.3% lower, RR 0.90, p = 0.84, treatment 13 of 116 (11.2%), control 15 of 120 (12.5%), NNT 77.
risk of no recovery, 19.7% lower, RR 0.80, p = 0.15, treatment 45 of 116 (38.8%), control 58 of 120 (48.3%), NNT 10, day 7, primary outcome.
