Prospective study of 200 hospitalized patients in Italy, showing 80% of patients had vitamin D deficiency. There was no significant differences in outcomes based on vitamin D levels. There was also no significant difference in vitamin D levels when compared with sepsis patients.
risk of death, 17.5% lower, RR 0.82, p = 0.58, high D levels (≥12ng/ml) 94, low D levels (<12ng/ml) 106, model 3, Table S2, Cox proportional hazards.
risk of death, 13.9% lower, RR 0.86, p = 0.73, high D levels (≥20ng/ml) 40, low D levels (<20ng/ml) 160, model 3, Table S2, Cox proportional hazards.
risk of death/ICU, 15.9% lower, RR 0.84, p = 0.53, high D levels (≥12ng/ml) 94, low D levels (<12ng/ml) 106, model 3, Cox proportional hazards.
risk of death/ICU, 10.9% lower, RR 0.89, p = 0.73, high D levels (≥20ng/ml) 40, low D levels (<20ng/ml) 160, model 3, Cox proportional hazards.
Effect extraction follows pre-specified rules prioritizing more serious outcomes.
