| "description": "VitalDB perioperative in-hospital mortality classification using 57 features available by the end of the operative/anesthesia case. ICU stay, hospital length of stay, admission/discharge timestamps and patient/case identifiers are excluded from X. Device/procedure indicators, grouped diagnoses and perioperative durations are retained; two invalid anesthesia durations are missing. ASA and laboratory missingness are preserved for training-fitted imputation. The stored patient-grouped, outcome-stratified fixed split is unchanged: 4,442/978/968 training/validation/test cases, containing 41/9/7 mortality-positive cases (57 cases from 48 patients). The small event counts limit validation and test precision.", | |
