The result of Survival analysis and Risk curve A The survival curves of all samples, B the survival curve of the training set, C the survival curve of the validation set; horizontal coordinates indicate survival time, vertical coordinates indicate survival rate. D-F risk curve, sample distribution map, and heat map for all sample sets, G-I risk curve, sample distribution map, and heat map for training sets, J-L risk curve, sample distribution map, and heat map for validation sets. Red dots indicate low risk or the sample is dead, blue dots indicate high risk or the sample is alive p < 0.05
