37th treatment shown to reduce risk in May 2022
 
*, now known with p = 0.00002 from 15 studies, recognized in 30 countries. Efficacy is variant dependent.
Lower risk for mortality, hospitalization, and cases.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
4,000+ studies for 60+ treatments. c19early.org
Retrospective immunocompromised patients, showing no significant difference between tixagevimab/cilgavimab and other mAbs.
Efficacy is variant dependent. In Vitro research suggests a lack of efficacy for omicron BA.2.75.2, BA.4.6, BQ.1.1 Planas, BA.5, BA.2.75, XBB Haars, ХВВ.1.9.1, XBB.1.9.3, XBB.1.5.24, XBB.1.16, XBB.2.9, BQ.1.1.45, CL.1, and CH.1.1 Pochtovyi.
This study is excluded in the after exclusion results of meta analysis: study compares against another treatment showing significant efficacy.
risk of death, 368.4% higher, RR 4.68, p = 0.32, treatment 1 of 19 (5.3%), control 1 of 89 (1.1%), day 14.
risk of hospitalization, 33.1% lower, RR 0.67, p = 1.00, treatment 1 of 19 (5.3%), control 7 of 89 (7.9%), NNT 38, day 14.
risk of no viral clearance, 23.7% higher, RR 1.24, p = 0.30, treatment 14 of 19 (73.7%), control 53 of 89 (59.6%), day 14.
