Statistical Analysis
All data are presented as means, standard deviations (SDs), or proportions. The variables were compared with the one-way analysis of variance (ANOVA) followed by post hoc tests using the Bonferroni correction (Kruskal –Wallis test when appropriate) or chi-squared test (Fisher’s exact test, if an inadequate number of assumptions). A Kaplan-Meier analysis was performed to assess the recurrence-free survival, and a log-rank test was used to compare the groups. All analyses were performed using IBM®SPSS® software, version 26 (IBM Corporation, Armonk, NY, USA), and a value of p < 0.05 was considered statistically significant.
