Statistical analysis
Statistical analysis was performed using a statistical package for social sciences (SPSS, version 27.0, IBM Corporation, Armonk, NY, USA). The Kolmogorov–Smirnov test was used to evaluate the normality of data distribution. Parametric variables are recorded as mean ± standard and comparisons were made using the two-sample independent t-test. Continuous variables were analyzed using the Mann-Whitney U test and reported as median (interquartile range - IQR). Values presented as number (percentage, %) and comparisons were made using the chi-square test or Fisher’s exact test. The Hodges-Lehmann estimator was used to calculate the 95% confidence interval (CI) for the median difference. GraphPad Prism 8.0 (GraphPad Software, CA, USA) were used to draw all figures in this study. A p value < 0.05 was identified as statistically significant differences.According to previous studies, an 8-point difference for the QoR-15 score signifies a clinically significant improvement [
