"description": "Urinary NMR classification of gastric cancer (GC=1; 43 samples) versus healthy controls (HE=0; 40 samples). Retain 52 of 149 source features using the CIMCB workflow criteria QC_RSD < 20% and Perc_missing < 10% from the supplied Peak sheet. Benign and quality-control samples are excluded. Feature values are log1p transformed; missing measurements are preserved for training-fitted preprocessing. The existing five stratified outer folds and three inner folds are retained. Sample IDs and source annotations are metadata, never features.",
