The correlation between risk score estimated by nomogram and tumor microenvironment (TME) and immune checkpoints (ICs) in the training cohort. (a) Distribution of risk score, TME score, ICs, and cancer-associated fibroblast (CAF) related gene expression level. R package “estimate” was used to calculate TME, immune, and stromal scores in each ESCC patient based on gene expression levels. (b) The relationship between risk score and TME, ICs (a) and CAFs (b). The size of the dot represents the size of the correlation coefficient, and the color scale from blue to yellow represents the P value from large to small.
