β (95% CI) indicates the regression coefficient, or difference and slope over time of mean glucose (mmol/l and mg/dl) and maximum glucose (in mmol/l and mg/dl ) difference per day, respectively, for ICU non-survivors, with ICU survivors as reference. Model 1: Crude analysis. Model 2: adjusted for age, sex, body mass index (BMI) and APACHE II score, chronic kidney, pulmonary and liver diseases, and cardiovascular risk factors
CI: Confidence Interval, ICU: Intensive Care Unit;
*Data on BMI (n = 3) and cardiovascular risk factors (n = 3) were missing; hence model 2 included 226
