Retrospective 56 patients in Turkey showing greater need for oxygen therapy and higher mortality with vitamin D deficiency, and significantly lower risk of pneumonia with vitamin D supplementation.
risk of death, 80.6% lower, RR 0.19, p = 0.23, high D levels 0 of 29 (0.0%), low D levels 2 of 27 (7.4%), NNT 14, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm), >=20ng/mL.
risk of oxygen therapy, 73.4% lower, RR 0.27, p = 0.07, high D levels 2 of 29 (6.9%), low D levels 7 of 27 (25.9%), NNT 5.3, >=20ng/mL.
