Retrospective hospitalized patients in the United Arab Emirates, showing no significant difference in viral clearance with different combinations of HCQ, AZ, favipiravir, and lopinavir/ritonavir.
viral clearance time, 3.1% higher, HR 1.03, p = 0.09, treatment 59, control 1,446, HCQ + favipiravir, Cox proportional hazards.
viral clearance time, 58.7% lower, HR 0.41, p = 0.09, treatment 4, control 1,446, HCQ + favipiravir + lopinavir/ritonavir, Cox proportional hazards.
