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.
