Figure 2. Construction of prognostic Risk score for OS patients. (A) Totally 7 genes were significantly related to the prognosis of OS. HR: Hazard ratio; 95% CI: 95% confidence interval. (B) The smallest lambda in LASSO Cox regression analysis was corresponding to the optimal number of genes. (C, D) Kaplan Meier survival curves of OS patients in GSE21257 and meta-GEO datasets, respectively. P was calculated based on log-rank test.
