Retrospective 226 COVID-19 pneumonia patients, 110 treated with favipiravir, showing higher mortality (p
=0.1) and ICU admission (p
=0.02) with treatment in multivariate analysis.
Almoosa et al., 8/24/2021, retrospective, Saudi Arabia, Middle East, peer-reviewed, 14 authors.
risk of death, 42.3% higher, RR 1.42, p = 0.10, treatment 33 of 110 (30.0%), control 24 of 116 (20.7%), adjusted per study, odds ratio converted to relative risk, overall mortality, multivariate binary logistic regression.
risk of ICU admission, 90.0% higher, RR 1.90, p = 0.02, treatment 110, control 116, adjusted per study, multivariate binary logistic regression, RR approximated with OR.
recovery time, 10.9% higher, relative time 1.11, p = 0.17, treatment 110, control 116.
Effect extraction follows pre-specified rules
prioritizing more serious outcomes. For an individual study the most serious
outcome may have a smaller number of events and lower statistical signficance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
