Small prospective study of 30 ICU patients, showing higher mortality risk for low vitamin D levels. When divided into two groups at the median level, there was 5 of 15 deaths for the low vitamin D group compared to 0 of 15 in the high vitamin D group.
risk of death, 90.9% lower, RR 0.09, p = 0.04, high D levels 0 of 15 (0.0%), low D levels 5 of 15 (33.3%), NNT 3.0, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm), >15.2ng/mL.
Effect extraction follows pre-specified rules prioritizing more serious outcomes.
