Retrospective 120 hospitalized patients in Spain showing no significant differences for vitamin D deficiency.
risk of mechanical ventilation, 35.0% lower, RR 0.65, p = 0.21, high D levels 15 of 27 (55.6%), low D levels 18 of 78 (23.1%), adjusted per study, inverted to make RR<1 favor high D levels, odds ratio converted to relative risk, ≥20 ng/mL, bivariate logistic regression.
risk of ICU admission, 16.9% lower, RR 0.83, p = 0.58, high D levels 11 of 27 (40.7%), low D levels 17 of 78 (21.8%), adjusted per study, inverted to make RR<1 favor high D levels, odds ratio converted to relative risk, ≥20 ng/mL, bivariate logistic regression.
