RCT on calcifediol (25-hydroxyvitamin D) treatment for hospitalized COVID-19 patients showing significantly reduced intensive care unit admissions.
All patients received standard care including HCQ+AZ. Significantly lower ICU admission with the addition of calcifediol - adjusted odds ratio 0.03 [0.003-0.25]. No deaths for calcifediol (0/50), 2 deaths for SOC (2/26).
For additional analysis see [1].

Castillo et al., 8/29/2020, Randomized Controlled Trial, Spain, Europe, peer-reviewed, 7 authors, dosage calcifediol 0.5mg day 1, 0.27mg day 3, 0.27mg day 7, and then weekly until discharge or ICU admission.
risk of death, 85.4% lower, RR 0.15, p = 0.11, treatment 0 of 50 (0.0%), control 2 of 26 (7.7%).
risk of ICU admission, 94.2% lower, RR 0.06, p = 0.001, odds ratio converted to relative risk.
