Figure 5. Risk-stratified analysis of the three-lncRNA signature for bladder cancer patients. Kaplan-Meier analysis of patients in the stage-II subgroup (A), stage-III subgroup (B), stage-IV subgroup (C), ≥65-year-old subgroup (D) and <65-year-old subgroup (E). The tick-marks on the curve represent the censored subjects. The differences between the two risk groups were assessed with two-sided log-rank tests.
