Statistical analysis
Data were analyzed using SPSS version 25.0 (SPSS®, IL, USA). The compliance of the data with the normal distribution curve was evaluated using the Shapiro-Wilk test. Continuous variables were compared using Student’s t-test and Mann-Whitney Utest, and categorical data were compared using the chi-square test. For the comparison of the preoperative and postoperative data within the groups, the t-test and Wilcoxon test were used in dependent groups. P <0.05 was considered statistically significant.
