et al., Revista de Sanidad Militar,
Retrospective 172 hospitalized COVID-19 patients in Mexico, reporting a very high prevalence of vitamin D deficiency, and significantly higher mortality with low vitamin D levels in unadjusted results.
risk of death, 61.7% lower, RR 0.38, p = 0.006, high D levels (≥8ng/mL) 21 of 137 (15.3%), low D levels (<8ng/mL) 14 of 35 (40.0%), NNT 4.1, inverted to make RR<1 favor high D levels (≥8ng/mL), odds ratio converted to relative risk.
