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.

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 increases mortality, morbidity, and collateral damage. We do not provide medical advice. Before taking any medication, consult a qualified physician who can provide personalized advice and details of risks and benefits based on your medical history and situation.
