Limitations of the study
This is a single-institution clinical cohort study of a relatively small number of transplanted patients. The statistical power to determine post-transplant differences in outcomes is limited, and it may be subjected to chance. The calculation of long-distance donor scores is compromised by the unavailability of echocardiography and coronary angiograms. Posttransplant outcomes are worse than reported by the International Society for Heart and Lung Transplantation database, but they are compatible with the Brazilian Transplant Registry. Reasons for that were not the scope of this paper.
