Comparison of the AUROC for 21-day, 42-day, and 90-day survival among the three prognostic tools. a, The AUROC values for 21-day survival were 0.709 for the PPI, 0.707 for the PS-PPI, and 0.734 for the ChPS. The best cutoff scores for 21-day survival were 4.5 for the PPI, 6 for the PS-PPI, and 39 for the ChPS. b, The AUROC values for 42-day survival were 0.688 for the PPI, 0.687 for the PS-PPI, and 0.709 for the ChPS. The best cutoff scores for 42-day survival were 4 for the PPI, 6 for the PS-PPI, and 35 for the ChPS. c, The AUROC values for 90-day survival were 0.668 for the PPI, 0.667 for the PS-PPI, and 0.697 for the ChPS. The best cutoff scores for 90-day survival were 4 for the PPI, 4.5 for the PS-PPI, and 38 for the ChPS. d, Comparison of the AUROC values for 7-, 14-, 21-, 30-, 42-, 60-, 90-, 120-, 150- and 180-day survival among the three prognostic tools. # *AUROC are significantly higher in the ChPS than both PPI and PS-PPI. * P < 0.05, ChPS versus PPI; # P < 0.05, ChPS versus PS-PPI. Abbreviation: AUROC, Area Under the Receiver Operating Characteristic Curve; PPI, Palliative Prognostic Index; PS-PPI, Performance Status-Based Palliative Prognostic Index; ChPS, Chinese Prognostic Scale
