Heatmaps generated by unsupervised hierarchical clustering of the 12 selected features of the VAT model in the (a) training cohort and (b) total validation cohort, respectively. The feature values are standardized to the range of [0, 1] in order to achieve a clear view. Each row of the heatmap is one selected radiomics feature, and each column is a sample (PNR, red; PR, blue). At the top, generated dendrogram represents samples with similar information determined by clustering (PNR, primary nonresponse; PR, primary response to infliximab therapy; VAT model, radiomics model based on features extracted from visceral adipose tissue)
