Dark and light gray color shade indicate that 1‐year graft survival rate ≤50% and 50% < 1‐year graft survival rate <80%, respectively. Abbreviations: DDLT, deceased donor liver transplantation; JRI, Japan Risk index; JRI‐D, JRI for donor; JRI‐S, JRI for surgery; JRI‐R, JRI for recipient; MELD, Model for End‐Stage Liver Disease.
JRI‐D = exp ([0.390 if donor age 60‒69] + [0.869 if donor age ≥70] + [0.262 if catecholamine index 10.0‒29.9] + [0.642 if catecholamine index ≥30.0] + [0.518 if donor maximum sodium ≥180 mEq/L] + [0.079 if donor maximum total bilirubin 3.0‒4.9 mg/dL] + [0.544 if donor maximum total bilirubin ≥5.0 mg/dL]).
JRI‐R = exp ([0.545 if re‐transplantation] + [0.291 if MELD30‒39] + [0.473 if MELD ≥40 ]+ [0.383 if recipient ICU]).
JRI‐S = exp ([0.923 if total ischemic time 11.0‒12.9 h] + [1.152 if total ischemic time ≥13.0 h]).
