  Fig. 2. A Comparison of total QoR-15 scores in the groups for the pre-operation and the first 3 days after surgery. Range 0–150, higher score indicates better recovery. B Comparison of each dimension varies of QoR-15 scores in the groups for the pre-operation and the first 3 days after surgery. Abbreviations: POD, postoperative day; pre-op, pre-operation; QoR-15, 15-item quality of recovery scale. Mann-Whitney U test or repeated measures analysis of variance was used. Compared with group I, *indicated statistical significance (P < 0.05); compared with group II, # indicated statistical significance(P < 0.05); and the P value was corrected using Bonferroni’s method

  Fig. 3. Comparison of patient satisfaction in each group on discharge day (A) and the 30 days after discharge (B). Range 0–7, higher degree indicates better patient satisfation. Mann-Whitney U test was used. *Indicated statistical significance (P < 0.001), and the P value was corrected using Bonferroni’s method

  Fig. 4. Nomogram to predict risk of postoperative complication. A Each factor corresponds to a specific point by drawing a line straight upward to the Points axis. The probability of postoperative complication is the point by drawing a line straight down to the bottom axis from the sum of the points on the Total Points axis. Calibration curve and ROC curve of the nomogram prediction model. B Calibration curve. The dashed line represents the ideal fit; the solid line represents the actual fit (C) ROC curve. (AUC = 0.906)
