  1. Kruskal-Wallis test for ordinal variables and Pearson’s chi-square test for nominal variables to compare between four different resection grade groups. Logistic regression analyses for multivariate analysis. The adjusted OR was obtained by logistic regression. The correlation between the variables and resection grade was detected by Spearman’s correlation analysis.
  2. OR odds ratios, CI confidence interval
