Retrospective 464 patients in United Arab Emirates showing low D levels at first hospital visit associated with higher COVID-19 severity and mortality.
risk of death, 59.3% lower, RR 0.41, p = 0.048, 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 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.
