Colchicine for COVID-19
6th treatment shown to reduce risk in September 2020
*, now known with p = 0.00000056 from 50 studies.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
3,800+ studies for 60+ treatments.
RCT 122 hospitalized patients in India, showing improved recovery with colchicine treatment. All patients received aspirin. There was one death and higher progression in the colchicine arm, however 3 patients in the colchicine arm had baseline ordinal scores ≥5, while no patients in the control arm did.
risk of death, 169.4% higher, RR 2.69, p = 1.00, treatment 1 of 62 (1.6%), control 0 of 43 (0.0%), continuity correction due to zero event (with reciprocal of the contrasting arm).
risk of progression, 108.1% higher, RR 2.08, p = 0.64, treatment 3 of 62 (4.8%), control 1 of 43 (2.3%).
recovery, 7.3% lower, RR 0.93, p = 0.21, treatment 62, control 43, relative improvement in ordinal score.
risk of no recovery, 15.0% lower, RR 0.85, p = 0.06, treatment 49 of 62 (79.0%), control 40 of 43 (93.0%), NNT 7.1, ordinal score ≤1.
recovery, 24.3% lower, RR 0.76, p = 0.02, treatment 62, control 43, relative improvement in CT score.
