FIGURE 6.
Relationship between the prognostic signature and clinicopathological factors of PCa patients. (A) The heat map shows the expressions of the five costimulatory molecule genes and clinicopathological factors in the high- and low-risk groups. The univariate (B) and multivariate (C) Cox regression analyses of clinicopathological factors (including the risk score) and prognosis. The bar chat showed that the prognostic signature had significantly different in different clinical subgroups, and the PCa patients with advanced age (D), high pathological T stage (E), node metastasis (F), high Gleason score (G), high prostate-specific antigen (H), and recurrence (I) tend to have a high risk score. ns: P > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
