Figure 1. Survival by age and congestive heart failure in children with Noonan syndrome and hypertrophic cardiomyopathy.

Figure 1

Estimated survival since diagnosis of hypertrophic cardiomyopathy (CM) in 74 children with Noonan syndrome by age and congestive heart failure (CHF) status at the time of HCM diagnosis. Log-rank P < .001. The size of the risk set is shown below the x-axis. The subgroup of 3 cases with congestive heart failure who were diagnosed at age ≥6 months is not shown (one known to survive 5.5 months post diagnosis, and 2 were not seen after diagnosis).
