Treatment with 25-hydroxyvitamin D3 (calcifediol) is associated with a reduction in the blood neutrophil-to-lymphocyte ratio marker of disease severity in patients hospitalized with COVID-19: a pilot, multicenter, randomized, placebo-controlled double blind clinical trial

RCT 106 hospitalized patients with vitamin D levels <30ng/ml in Iran, 53 treated with calcifediol, showing that treatment was able to correct vitamin D deficiency/insufficiency, resulting in improved immune system function. Hospitalization, ICU duration, ventilation, and mortality was lower with treatment, without reaching statistical significance with the small sample size. The dosage used in this trial was much lower than other trials.
risk of death, 40.0% lower, RR 0.60, p = 0.72, treatment 3 of 53 (5.7%), control 5 of 53 (9.4%), NNT 26.
risk of mechanical ventilation, 60.0% lower, RR 0.40, p = 0.44, treatment 2 of 53 (3.8%), control 5 of 53 (9.4%), NNT 18.
risk of ICU admission, 40.0% lower, RR 0.60, p = 0.42, treatment 6 of 53 (11.3%), control 10 of 53 (18.9%), NNT 13.
ICU time, 36.4% lower, relative time 0.64, p = 0.20, treatment 53, control 53.
hospitalization time, 16.7% lower, relative time 0.83, p = 0.10, treatment 53, control 53.
Effect extraction follows pre-specified rules prioritizing more serious outcomes.
