Retrospective 115 hospitalized patients in Brazil, showing lower mortality with higher vitamin D levels. Adjusted results are only provided for vitamin D as a continuous variable.
risk of death, 57.1% lower, RR 0.43, p = 0.046, high D levels (≥50nmol/L) 12 of 87 (13.8%), low D levels (<50nmol/L) 9 of 28 (32.1%), NNT 5.4.
risk of ICU admission, 19.5% higher, RR 1.20, p = 0.81, high D levels (≥50nmol/L) 26 of 87 (29.9%), low D levels (<50nmol/L) 7 of 28 (25.0%).
