The associations between serum vitamin D concentration and individual cardiac morbidities among 426 cardiac surgical patients.

IABP = Intra-aortic balloon pump, ECMO = Extra corporeal membrane oxygenator, VT/VF = Ventricular tachycardia/Ventricular fibrillation.*Odds ratio for a 5-unit increase in vitamin D concentration, after adjusting for potential confounders: age, gender, race, body mass index, smoking status, dialysis, and ethanol alcohol (ETOH).†A Bonferroni correction was used to adjust for multiple testing. Thus, the 99.55% CIs are presented, and the significance criterion for each individual outcome is Pa priori criteria for statistical significance.
