**Figure 3.** **Identification and assessment of immune-related lncRNA prognostic signature for bladder cancer.** (**A**) The HR and p-value of selected genes in the immune terms using the univariable Cox HR regression (Criteria: *p*-value <0.05). (**B**) The LASSO Cox analysis identified 19 lncRNAs most related to prognostics. (**C**) The 10-round cross-validation determined the optimal values of the penalty parameter. (**D**) The HR and *p*-value from the multivariable Cox HR regression prognostic signature. (**E**) Patients showed poor overall survival (OS) in the high-risk group (red) than those in the low-risk group (blue). (**F**) The risk curve of each sample reordered by risk score. (**G**) A sample survival overview using the scatter plot. The green dots represent survival and red represent death, respectively. (**H**) Heatmap showed the expression of the signature in the high-risk groups and low-risk groups. The pink and blue bars represented the low-risk group and the high-risk group. And the evolution from green to red represented the 0 to 6 level of gene expression.
