Figure 2. Estimated cumulative incidence rates for echocardiographic normalization in the presence of the competing risk for death or transplant among 1953 children with dilated cardiomyopathy. A) Early cohort (diagnosed between 1990 and 1999). B) Late cohort (diagnosed between 2000 and 2009).
At any given time, the probabilities associated with the 4 states sum to 1.0. Although the rates of echocardiographic normalization and transplantation were similar between cohorts (p = 0.22 and p = 0.35, respectively), the early cohort had a higher death rate (p = 0.04).
