Fig. 2 Graph of the cluster ratios calculated within each grade in the training cohort (a) and validation cohort (b) by observer 1. The cluster ratios show a significant association with histological grade. There was a significant positive correlation between the cluster 1 ratio and histological

grade in both training and validation cohorts; the higher the grade, the higher the cluster 1 ratio was. There was a significant negative correlation between the cluster 3 ratio and histological grade in both training and validation cohorts; the higher the grade, the lower the cluster 3 ratio
