Retrospective 154 consecutive COVID-19 patients in Mexico, showing low vitamin D levels associated with higher mortality.
This is the 126th of 175 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 18 vigintillion).
risk of death, 52.2% lower, OR 0.48, p = 0.04, cutoff 20ng/mL, adjusted per study, multivariable, RR approximated with OR.

Introduction: One of the functions of vitamin D is to regulate respiratory epithelium inflammatory response; therefore, deficiency of this vitamin in the context of COVID-19 could constitute a predictive biomarker of the disease outcome. Objective: To evaluate the usefulness of vitamin D for predicting mortality in patients with COVID-19. Methods: Observational, retrospective study in which 154 patients diagnosed with COVID-19 were included, out of whom 111 survived and 43 died. Vitamin D concentration was determined in all of them. Results: A log-rank p-value < 0.032 was obtained for survival when vitamin D concentration was used as a categorical variable (≤ 20 ng/mL and > 20 ng/mL). On Cox proportional analysis, age and vitamin D concentration were shown to be risk factors associated with mortality in patients with COVID-19
