ROC curves for response prediction of Scores A and B (A) ROC curve was drawn for response prediction of Score A (AUC = 0.776, 95% CI 0.633–0.919). (B) ROC curve was drawn for response prediction of Score B (AUC = 0.881, 95% CI 0.743–1.000). ROC, receiver operating characteristic, Score A = Tregs ÷ (CD4⁺/CD8⁺ ratio), Score B = Tregs × HLA-DR⁺CD4⁺ T cells × PD1⁺CD8⁺ T cells, AUC, area under the curve.
