33rd treatment shown to reduce risk in February 2022
 
*, now known with p = 0.023 from 4 studies.
Lower risk for recovery.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.

Observational study of 43 patients >= 50 years old, with 17 patients receiving vitamin D, magnesium, and vitamin B12 (DMB); and 26 control patients, showing a significantly lower need for oxygen therapy and ICU admission with treatment. DMB OR 0.20 [0.04–0.93] for oxygen therapy and/or intensive care support with multivariate analysis.
This study is excluded in meta analysis: combined treatments may contribute more to the effect seen.
Study covers vitamin B12 and vitamin D.
risk of oxygen therapy, 80.5% lower, RR 0.20, p = 0.04, treatment 3 of 17 (17.6%), control 16 of 26 (61.5%), NNT 2.3, adjusted per study, multivariate.
risk of ICU admission, 80.9% lower, RR 0.19, p = 0.07, treatment 1 of 17 (5.9%), control 8 of 26 (30.8%), NNT 4.0, no adjusted result available.
