Figure 3. Estimated cumulative incidence rates for echocardiographic normalization by age at diagnosis.

The cumulative incidence for recovery of normal echocardiographic function and size is lowest in children diagnosed after 10 years old (10% by 2 years; Figure 3C) and similar for the two younger age groups: 24% for those diagnosed before age 1 year (Figure 3A) and 26% for those diagnosis before between 1 and 10 years (Figure 3B). Black lines, echocardiographic normalization; red lines, death-or-transplant; green lines, persistently abnormal echocardiogram.
