COVID-19 Disease Severity and Death in Relation to Vitamin D Status among SARS-CoV-2-Positive UAE Residents
Retrospective 464 patients in United Arab Emirates showing low D levels at first hospital visit associated with higher COVID-19 severity and mortality.
AlSafar et al., 5/19/2021, retrospective, United Arab Emirates, Middle East, peer-reviewed, 8 authors.
risk of death, 59.3% lower, RR 0.41, p = 0.05, high D levels 16 of 337 (4.7%), low D levels 10 of 127 (7.9%), adjusted per study, odds ratio converted to relative risk, >=12ng/mL.
risk of COVID-19 severe case, 33.2% lower, RR 0.67, p = 0.005, high D levels 337, low D levels 127, adjusted per study, odds ratio converted to relative risk, >=12ng/mL.
Effect extraction follows pre-specified rules
prioritizing more serious outcomes. For an individual study the most serious
outcome may have a smaller number of events and lower statistical signficance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.

practical, effective, and safe means should be used. Elimination of COVID-19
is a race against viral evolution. No treatment, vaccine, or intervention is
100% available and effective for all current and future variants. Denying the
efficacy of any method increases the risk of COVID-19 becoming endemic; and
