CHD congenital heart disease, CI confidence interval, ICC intraclass correlation coefficient, NA non applicable (range of items was not indicated in summary scores), SD standard deviation
% ceiling indicates the percentage of scores at the maximum value of the scaling range for each dimension
Mean difference = mean controls − mean CHD patients. *P-value < 0.05; **P-value < 0.01; ***P-value < 0.001
Effect size = mean difference ÷ pooled SD ([0.2; 0.5], small effect size; [0.51; 0.80], moderate effect size; > 0.80, large effect size)
