Construction of the prognosis risk prediction model in the training cohort. A, Twelve candidate genes screened out by LASSO analysis with minimal lambda. B, Distribution of risk score and survival status of each osteosarcoma patient in the high risk and low risk groups. C, Heatmap visualizing the expression matrix of the 12 candidate genes in the 2 groups. D‐L, Comparisons between the 2 groups in terms of stomal score, immune score, ESTIMATE score, tumor purity, abundance of immune filtrating cells in tumor tissues and survival curve of the patients. M, Time‐dependent ROC curve of the constructed model
