Counts are expressed as n (%), continuous variables are expressed as median (interquartile range). Medians were compared using Student t or Wilcoxon–Mann–Whitney U tests for continuous variables, as appropriate. Categorical variables were compared using the χ2 or Fisher exact test. ISVMP indicates infant single‐ventricle management and monitoring program; WAZ, weight‐for‐age Z score.
