Real-World Effectiveness and Tolerability of Monoclonal Antibody Therapy for Ambulatory Patients with Early COVID-19
Real-World Effectiveness and Tolerability of Monoclonal Antibody Therapy for Ambulatory Patients with Early COVID-19
Retrospective 115 patients treated with casirivimab/imdevimab showing lower mortality, hospital admission, and emergency department visits with treatment. Authors falsely state that "no other COVID-19 therapies for ambulatory patients have proven effective".
risk of death, 98.3% lower, RR 0.02, p = 0.63, treatment 0 of 115 (0.0%), control 57 of 5,536 (1.0%), relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).
risk of hospitalization, 91.1% lower, RR 0.09, p < 0.001, treatment 1 of 115 (0.9%), control 538 of 5,536 (9.7%).

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 significance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
Please send us corrections, updates, or comments. Vaccines and treatments are both extremely valuable and complementary. All
practical, effective, and safe means should be used. Elimination of COVID-19
is a race against viral evolution. No treatment, vaccine, or intervention is
100% available and effective for all current and future variants. Denying the
efficacy of any method increases the risk of COVID-19 becoming endemic; and
increases mortality, morbidity, and collateral damage. We do not provide
medical advice. Before taking any medication, consult a qualified physician
who can provide personalized advice and details of risks and benefits based
on your medical history and situation. Treatment protocols for physicians are
