**Figure 2.** **Development and validation of aging-related lncRNAs prognosis signature.** (**A**) LASSO regression of 15 aging-related lncRNAs. (**B**) Cross-validation for tuning the parameter selection in the LASSO regression. (**C**) Coefficient of prognosis model regression. (**D**) Kaplan-Meier curves of high-risk group and low-risk group in CGGA. (**E**) Distribution of risk score and patients based on the risk score in CGGA. (**F**) The tSNE2 method showed obvious two components in CGGA. (**G**) Kaplan-Meier curves of high-risk group and low-risk group in TCGA. (**H**) Distribution of risk score and patients based on the risk score in TCGA. (**I**) The tSNE2 method showed obvious two components in TCGA. (**J** and **K**) ROC curves of prognostic signature based on risk score in CGGA and TCGA.
