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.
