Retrospective 33 COVID-19 hospitalized patients in North Macedonia, showing significantly lower vitamin D levels for severe vs. moderate cases. Oxidative stress was also higher for vitamin D insufficient patients.
risk of death, 40.7% lower, RR 0.59, p = 0.68, high D levels (≥30ng/mL) 2 of 9 (22.2%), low D levels (<30ng/mL) 9 of 24 (37.5%), NNT 6.5.
risk of severe case, 59.0% lower, RR 0.41, p = 0.13, high D levels (≥30ng/mL) 2 of 9 (22.2%), low D levels (<30ng/mL) 13 of 24 (54.2%), NNT 3.1.
