PROLIFERATION, HEAT
Baseline characteristics were compared between the allocated groups using Pearson’s chi-square for categorical data and one-way ANOVA or Kruskal–Wallis tests for continuous data, where appropriate. Unsupervised cluster analysis with ordered leaves was performed using the IRS of all stains and Ki-67 proliferation index and visualized in a dendrogram with heat map. The IRS of all stains was correlated with each other, the SUV
