RCT 44 treatment and 43 control patients with vitamin D levels <30ng/ml, showing significant reduction in inflammatory markers with treatment of 60,000IU vitamin D per day for 8 days (10 days for BMI >25). Death and ICU admission was lower in the treatment group but not statistically significant.
Lakkireddy et al., 2/23/2021, Randomized Controlled Trial, India, South Asia, peer-reviewed, mean age 45.5, 9 authors, dosage 60,000IU days 1-8, 8 or 10 days depending on BMI.
risk of death, 60.9% lower, RR 0.39, p = 0.27, treatment 2 of 44 (4.5%), control 5 of 43 (11.6%).
risk of ICU admission, 21.8% lower, RR 0.78, p = 0.74, treatment 4 of 44 (9.1%), control 5 of 43 (11.6%).
hospitalization time, 7.1% lower, relative time 0.93, p = 0.90, treatment 44, control 43.
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 signficance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
