Calibration curves for the nomograms for patients with metastatic gastric adenocarcinoma who undergo palliative gastrectomy. a: Bootstrap validation of postoperative prognostic nomogram with samples sizes of 200 in the development dataset. b: External validation of postoperative prognostic nomogram using the cohort of 407 patients with samples sizes of 130. c: Bootstrap validation of preoperative nomogram with samples size of 200 in the development dataset. d: External validation of preoperative nomogram using the 407-patient validation cohort. The 45-degree grey lines show the ideal reference lines where the predicted survival probabilities match the actual survival proportions. Dots indicate the predicted probabilities for the resampled groups of patients with their respective 95% confidence intervals
