Note: PSM: Propensity score matching; Pos−1 d: The first postoperative day. Glycemic variability is expressed as coefficient of variation (CV%), calculated as (standard deviation/mean glucose) × 100%. All glucose values were selected from patient records at approximately one hour postprandially, three times daily
