Fig. 10. Prediction performance of the pathway-based GC classification method. TCGA-STAD as the training set and ACRG-STAD and GSE84437 as test sets to predict the three subtypes by XGBoost⁸³.

The prediction accuracies and weighted sensitivity, specificity, and F1-scores in TCGA-STAD (tenfold cross-validation), ACRG-STAD, and GSE84437 are shown.
