Figure 2. Screening prognosis immune-related lncRNA for model construction. (A) Validation was performed for tuning parameter selection through the least absolute shrinkage and selection operator (LASSO) regression model for overall survival (OS). (B) Elucidation for LASSO coefficient profiles of prognostic lncRNAs. (C) Forest plot exhibited the hazard ratio (HR) with 95% confidence interval (95% CI) of prognostic immune-related lncRNA in BLCA on the basis of the multivariate Cox regression result.
