Establishment and validation of the prognostic model for disease-free survival based on significant DEGs; a Receiver operating characteristic curves of prognostic signature in the training cohort; b The survival curve showed the different disease-free status between high- and low-risk patients. c The heat map showed the expression of prognostic genes in the training cohort. d The risk curve of each sample reordered by risk score; e The scatter plot showed the disease-free status of osteosarcoma patients in the training cohort; f Receiver operating characteristic curves of prognostic signature in validation cohort; g The survival curve showed the different disease-free status between high- and low-risk patients. h The heat map showed the expression of prognostic genes in the validation cohort. i The risk curve of each sample reordered by risk score; j The scatter plot showed the disease-free status of osteosarcoma patients in the validation cohort
