Abstract
We retrospectively investigated the clinical outcomes of favipiravir in patients with COVID-19
pneumonia. Patients who between 23 May 2020 and 18 July 2020 received ≥24 hours of
favipiravir were assigned to the favipiravir group, while those who did not formed the nonPage 1 of 14
favipiravir group. The primary outcome was 28-day clinical improvement, defined as..
