Figure 4. The role of T cell-related signature (TRS) in predicting the prognosis of ovarian cancer. (A) C-index evaluated the overall survival rate of ovarian cancer patients in training and testing cohort. (B) Univariate and multivariate cox regression analysis considering grade, stage and TRS in training and testing cohort. (C) C-index of TRS and other established signatures evaluated discrimination of TRS in predicting the prognosis of ovarian cancer patients. (D, E) Prediction nomogram for predicting the 1-, 3-, and 5-year OS rate of ovarian cancer.
