Retrospective 379 bamlanivimab patients and 379 matched controls in the USA, showing no significant differences with treatment.
Efficacy is highly variant dependent. Unlikely to be effective for omicron [Liu, Sheward, VanBlargan].
risk of death, no change, RR 1.00, p = 1.00, treatment 6 of 379 (1.6%), control 6 of 379 (1.6%).
risk of hospitalization, 3.9% higher, RR 1.04, p = 0.86, treatment 79 of 379 (20.8%), control 76 of 379 (20.1%), all-cause hospital revisit.
risk of hospitalization/ER, 5.0% higher, OR 1.05, p = 0.86, treatment 379, control 379, RR approximated with OR.
