Comparison of postoperative blood glucose levels and glycemic variability (GV) between groups (values represent daily means of three postprandial measurements)
| Before PSM | P | After PSM | P | |||
|---|---|---|---|---|---|---|
| POCL Group (212) | Fasting Group (467) | POCL Group (205) | Fasting Group (205) | |||
| Pos−1 d | 11.05 [9.43–12.81] | 11.37 [9.73–13.17] | 0.066 | 11.03 [9.43–12.77] | 11.37 [9.77–13.20] | 0.045 |
| Pos−2 d | 8.15 [7.20–9.51] | 8.37 [7.13–10.15] | 0.347 | 8.13 [7.20–9.50] | 8.40 [7.13–10.13] | 0.258 |
| Pos−3 d | 7.68 [6.75–9.01] | 7.93 [6.67–9.70] | 0.312 | 7.67 [6.76–8.93] | 7.90 [6.64–9.68] | 0.209 |
| GV (%) | 20.48 [15.09–27.48] | 22.68 [16.09–29.42] | 0.182 | 20.39 [14.90–27.48] | 21.81[16.10–29.78] | 0.214 |
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
