Table 1. Peri-operative blood glucose control groups.
Patient characteristics, post-operative infection and Peri-operative Blood Glucose values according to optimal control (mean blood glucose ≤10 mmol/l) and sub-optimal control (mean blood glucose >10 mmol/l) groups. BMI = Body Mass Index (%), SEM = Standard Error of the Mean, *p < 0.05.
