Values are percentages. Missing <10% of outcomes except for Behavior Rating Inventory of Executive Function–Teacher (n=90) task. ADHD indicates attention‐deficit/hyperactivity disorder.
a
P values are determined by Fisher's exact tests.
b
Outcomes are based on those Fontan subjects (n=120) aged <17 years.
c
Outcomes are based on those Fontan subjects (n=36) aged ≥17 years.
