Construction of immune-related poor prognosis signature. A The distribution of PPS score, OS, and expression patterns of genes involved in the signature. B Kaplan–Meier curve of OS among PPS-high and PPS-low group patients. Log-rank statistic was conducted to test statistical significance. C Performance assessment of the PPS by AUC. ROC analysis revealed the AUC was 0.83 at 12 months, 0.894 at 36 months, and 0.869 at 60 months
