PSM retrospective 1,218 COVID-19 ICU patients in Saudi Arabia, showing no significant difference in mortality, and longer ICU/MV time with favipiravir treatment.
This study is excluded in the after exclusion results of meta analysis: very late stage, ICU patients.
risk of death, 17.0% higher, HR 1.17, p = 0.51, treatment 73, control 73, in-hospital, propensity score matching.
risk of death, 14.0% lower, HR 0.86, p = 0.53, treatment 73, control 73, propensity score matching, day 30.
ventilation time, 46.7% higher, relative time 1.47, p = 0.008, treatment 73, control 73, propensity score matching.
ICU time, 50.0% higher, relative time 1.50, p = 0.01, treatment 73, control 73, propensity score matching.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
