Figure 8. Further exploration of the expression of TICRR and PPIF. (A), Transcriptional expression of TICRR was significantly correlated with clinical stages and pathological grades of EC. ***p<0.001 compared with normal tissues. (B) Analysis of the correlation between the expression of TICRR and infiltrating immune cells (C), Correlation between PPIF and clinical stages and grades, respectively. ***p<0.001 compared with normal tissues. (D) Correlation between PPIF and immune cell populations. (E) Prognostic value of TICRR calculated by Kaplan-Meier analysis. (F) Overall survival analyzed using the Kaplan–Meier method with log-rank testing according to PPIF expression.
