Prognostic risk score signature construction. A Among the 11 genes screened by Cox regression, the left side represents the P value of each gene obtained by Cox regression, the middle is the gene, and the right side represents the HR value obtained by Cox regression (> 1 indicates a risk factor, and < 1 indicates a protective factor). B LASSO regression results show the dotted line position as 5. Five genes were screened to build the signature. C Results obtained by LASSO regression show that the dotted line position points to 5. Five genes were finally screened to build the signature. The horizontal axis of the five genes screened by LASSO regression represents the LASSO regression coefficient of each gene, which is the coefficient of each gene in the risk score
