Kaplan-Meier survival of International Society for Heart and Lung Transplantation (ISHLT) definition after adjustment for mechanical ventilation status. Demonstrated are comparisons of the ISHLT definition for the 72-hour discrete time point. Significance was determined by the log-rank test. Curves are discriminated by color: blue, no primary graft dysfunction (PGD); green, severe PGD reclassified as no PGD owing to absence of mechanical ventilation status; and red, severe PGD.
