Retrospective 69 hospitalized COVID-19 patients in Iran, showing lower vitamin D associated with higher mortality, ICU admission, and AKI in unadjusted results. The mean age of deficient patients was lower. Statistical significance is not reached for the binary comparison between the groups with levels <20 ng/mL and ≥20 ng/mL.
risk of death, 40.0% lower, RR 0.60, p = 0.28, high D levels (≥20ng/mL) 6 of 30 (20.0%), low D levels (<20ng/mL) 13 of 39 (33.3%), NNT 7.5.
risk of ICU admission, 39.3% lower, RR 0.61, p = 0.20, high D levels (≥20ng/mL) 7 of 30 (23.3%), low D levels (<20ng/mL) 15 of 39 (38.5%), NNT 6.6.
risk of AKI, 42.2% lower, RR 0.58, p = 0.13, high D levels (≥20ng/mL) 8 of 30 (26.7%), low D levels (<20ng/mL) 18 of 39 (46.2%), NNT 5.1.
