Continuous variables are expressed as the mean ± standard deviation according to the distribution of the data, and categorical variables are expressed as numbers (percentages). TOF, tetralogy of Fallot; GMV, gray-matter volume; WMV, white-matter volume; TIV, total intracranial volume; CSF, cerebrospinal fluid.
