Multivariate model adjusted for sex, age and Charlson comorbidity index. Odds ratios (OR) were estimated for increasing 25(OH)D concentrations from the lower quartile (21.5 nmol/L) to the upper quartile (47.7 nmol/L). Abbreviations: CI, confidence interval; CAI, catheter-associated bloodstream infection; HAI, hospital-acquired infection; HCAP, health-care associated pneumonia; ICU, intensive care unit; N, number of patients; UTI, urinary tract infection; SSI, surgical site infection.
