RCT 156 patients in Japan, 107 treated with favipiravir, showing significant improvement in a composite outcome defined as the time to improvement in temperature, SpO2, CT findings, and recovery to PCR-.
time to improvement, 37.1% lower, HR 0.63, p = 0.01, treatment 107, control 49, adjusted per study, Cox proportional hazards, composite time to improvement in temperature, SpO2, CT findings, and recovery to PCR-.
time to improvement, 58.5% lower, HR 0.41, p = 0.01, treatment 47, control 13, adjusted per study, <5 days from onset of fever, Cox proportional hazards, composite time to improvement in temperature, SpO2, CT findings, and recovery to PCR-.
