AUX1: Normal head circumference and height; AUX2: Isolated Macrocephaly; AUX3: Macrocephaly and Tall Stature; AUX4: Isolated Tall Stature.
Tall Stature is strongly unrelated to the ASD “simplex” group, and is associated with the ASD-EEG group (see CA in Table S5 in Supporting Information S1). **Isolated Tall Stature (AUX4) is associated with EEG abnormalities; concurrence of Tall Stature and Macrocephaly (AUX3) is associated to seizures; Isolated Macrocephaly (AUX 2) is equally distributed among groups (see CA in Table S6 in Supporting Information S1).
Φc = Cramers’ phi coefficient, χ2 = the Pearson chi-squared test.
