Donor-recipient age mismatch and outcomes in liver transplantation: A scientific registry of transplant recipients database analysis

Figure 1 Donor characteristics and comorbidities by donor:recipient type. There were differences in donor characteristics between donor:recipient age pairs. The most common causes of death in donors were cerebrovascular accident, while anoxia and head trauma were more common in younger donors (P < 0.001). Older donors had higher rates of comorbidities such as diabetes and hypertension. High-risk organ donors, donation after cardiac death, and living donor liver transplantation were more likely to be of younger donor:recipient age pairs (P < 0.001). YAD: Younger age donors, ≤ 45-years; MAD: Middle-aged donors, 46-69-years; OAD: Older age donors, ≥ 70-years; YAR: Younger age recipients, ≤ 55-years; OAR: Older age recipients, > 55-years; CVA: Cerebrovascular accident; DCD: Donation after cardiac death; LDLT: Living donor liver transplantation.
