Establishment and validation of nomogram to predict the risk of peritoneal metastasis in gastric cancer patients. a A nomogram integrating with weight loss, CA19-9, CA-125, lymphocytes count number, and H5N5F1E2 level was created to predict risk of peritoneal metastasis. b Calibration curve for nomogram-predicted and actual probability of having peritoneal metastasis. c Sensitivity and specificity for predicting peritoneal metastasis of nomogram model and other single variables was compared by the area under the Receiver operating characteristic (ROC) curve (AUC) and tested by Delong. Delong. Clarke-Pearson test. CA19-9, CA125, CA724: carbohydrate antigen 19-9, 125, and 724; H hexose, N N-acetylhexosamine, F fucose, L α 2,3-sialic acid, E α 2,6-sialic acid. ***P < 0.001
