Retrospective 545 hospitalized patients in Saudi Arabia, showing higher mortality with vitamin D deficiency, without statistical significance.
risk of death, 42.5% lower, OR 0.57, p = 0.46, high D levels (≥25ng/mL) 179, low D levels (<25ng/mL) 78, adjusted per study, multivariable, RR approximated with OR.
risk of ICU admission, 7.4% lower, OR 0.93, p = 0.80, high D levels (≥25ng/mL) 179, low D levels (<25ng/mL) 78, adjusted per study, multivariable, RR approximated with OR.
