Retrospective 551 moderate to severe COVID-19 patients in Mexico showing vitamin D ≤12ng/mL independently associated with COVID-19 mortality. No association was found between vitamin D levels and the need for intubation. Vitamin D deficiency was more prevalent in women and patients with type 2 diabetes.
risk of death, 52.6% lower, RR 0.47, p = 0.006, high D levels (≥12ng/mL) 95 of 494 (19.2%), low D levels (<12ng/mL) 21 of 57 (36.8%), NNT 5.7, adjusted per study.
