Note. CHD = congenital heart disease; TGA = dextro-transposition of the great arteries; TOF = tetralogy of Fallot; SVF = single-ventricle children/adolescents who underwent the Fontan procedure; OR = odds ratio; CI = confidence interval for the OR; C = control; TCC = Total Consecutively Correct; TPMR = Time-per-Move Ratio; MAR = Move-Accuracy Ratio; CCS = Confirmed Correct Sorts. Reference group = controls. Variables were dichotomized using 1.5 SD below population mean as cutoff score. Boldface denotes significant odds ratios. Only significant CHD-group pairwise comparisons are presented.
