DOI: 10.1097/xcs.0000000000000545

Abstract: BACKGROUND Elucidating contributors affecting liver transplant survival is paramount. Current methods offer crude global group outcomes. To refine patient-specific mortality probability estimation and determine covariate interaction using recipient and donor data, we generated a survival… read more here.
