BMI categories: underweight (<18.5 kg/m2), normal (18.5–24.9 kg/m2), overweight (25–29.9 kg/m2), obesity 1 (30–34.9 kg/m2), obesity 2 (35–39.9 kg/m2), and obesity 3 (>40 kg/m2). Data are reported as OR with 95% CIs.
*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.
