Retrospective 200 hospitalized COVID-19 patients in Saudi Arabia, showing no significant difference in outcomes between HCQ and favipiravir.
risk of death, 400.0% higher, RR 5.00, p = 0.49, treatment 2 of 37 (5.4%), control 0 of 37 (0.0%), continuity correction due to zero event (with reciprocal of the contrasting arm), propensity score matching.
hospitalization time, 42.9% lower, relative time 0.57, p = 0.63, treatment 37, control 37, propensity score matching.
time to discharge, 28.6% lower, relative time 0.71, p = 0.74, treatment 37, control 37, propensity score matching.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

HCQ and FPV were used early in the pandemic as a treatment modality for COVID-19. Various studies evaluated the HCQ and FPV effectiveness, based on the mortality endpoint and showed conflicting results. We hypothesize that analyzing the difference in the LOS as a significant endpoint would be of a major interest, especially for healthcare providers, to prevent a lengthy hospitalization and disease progression. Methods: This is a retrospective observational study, conducted via a medical chart review of COVD-19 patients who were admitted between April 2020 and March 2021 with a moderate to severe illness. The LOS endpoint was tested using the paired Wilcoxon signed-rank (WSR) model. Prior to using the WSR model, the balance..
