  1. Characteristic variables stratified by group. Categorical and binominal variables presented as number and percentage (n (%)). Mean and standard deviation (m (SD)) or median and interquartile range (m [IQR]) for continuous variables. The variable scanner software was a binominal categorical variable introduced to account for a scanner upgrade during the study.
  2. D-TGA d-Transposition of the Great Arteries, LVOTO left ventricular outflow tract obstruction, RVOTO right ventricular outflow tract obstruction, SVP single ventricle physiology.
  3. aExploratory p values show uncorrected p values, asterisks (*) indicate p value <0.05, the used test is specified in brackets as follows:
  4. (a) t-test, (b) Wilcoxon rank-sum test, and (c) χ2 test.
  5. bOther included: ventricular septal defect, L-TGA, truncus arteriosus communis, and total anomalous pulmonary venous connection.
