Retrospective 91 hospitalized patients in Pakistan, showing vitamin D deficiency associated with mortality in multivariate Cox regression.
risk of death, 53.1% lower, RR 0.47, p = 0.046, high D levels (≥10ng/mL) 73, low D levels (<10ng/mL) 18, multivariate Cox regression.
risk of mechanical ventilation, 19.4% lower, RR 0.81, p = 0.32, high D levels (≥10ng/mL) 5 of 73 (6.8%), low D levels (<10ng/mL) 6 of 18 (33.3%), NNT 3.8, adjusted per study, multivariate Cox regression.
risk of ICU admission, 32.9% lower, RR 0.67, p = 0.54, high D levels (≥10ng/mL) 73, low D levels (<10ng/mL) 18, multivariate Cox regression.
Effect extraction follows pre-specified rules prioritizing more serious outcomes.
