*Crude OR.
†Model 1 adjusted for age, gender, race, and BMI.
‡Model 2: model 1+hospital setting (ICU vs non-ICU), admission team (medical vs surgical), admission diagnosis, BG on admission, medical comorbidities, and Charlson comorbidity index.
BG, blood glucose; BMI, body mass index; ICU, intensive care unit.
