Validation of the autophagy-related lncRNA prognostic signature in the validation cohort. KM survival curves showed that patients in the high-risk group had significantly poorer overall survival (A). Principal component analysis showed that patients with different risks were significantly divided into two clusters; the red dots represented high-risk patients, whereas the blue dots represented low-risk patients (B). The time-dependent ROC curve showed that the AUC value for the prognostic signature was 0.685 (C). The distribution of risk scores between low- and high-risk groups; The red dots represented high-risk patients, whereas the green dots represented low-risk patients (D). The scatter plot showed the relationship between the risk score and survival time; The red dots represented high-risk patients, whereas the green dots represented low-risk patients (E).
