Addition of 25-hydroxyvitamin D levels to the Deyo-Charlson Comorbidity Index improves 90-day mortality prediction in critically ill patients

Continuous data were reported as means with standard deviations (SDs), medians with interquartile ranges (IQRs), and categorical values were expressed as proportions. Body mass index = BMI, Acute Physiology and Chronic Health Evaluation II = APACHE II; Deyo-Charlson Comorbidity Index = DCCI; intensive care unit = ICU
P-values in italics represent statistically significant results
