Calibration curves and DCA curves. Calibration curves for 1-year A, 3-year B, and 5-year C OS in the training cohort. The predicted possibility of the year-specific OS rate is indicated in the x-axis, and the actual possibility of the year-specific OS rate is indicated in the y-axis. DCA curves in the training cohort D. Clinical usefulness of different predictive systems in predicting overall survival at various time points. The y-axis represents net benefit. The x-axis shows threshold probability. The brown line displays the benefit of the developed nomogram. The light blue line displays the benefit of pleural metastasis. The faint yellow line displays the benefit of neutrophils. The deep yellow line displays the benefit of lymphocytes. The grey line displays the benefit of the B cells. The pink line displays the benefit of Treg cells. The green line displays the benefit of TNM
