ROI ANCOVAs controlling for Age, Head Circumference, and PIQ

Structure Mean
ASD (SD)
N=59		 Mean
TD (SD)
N=30		 F p ρη2
Thalamus 16.92 (1.46) 17.05 (2.17) 0.09 .76 .001
Precentral 30.84 (4.51) 31.48 (3.78) 0.35 .55 .004
Postcentral 21.28 (3.83) 21.91 (2.93) 1.06 .31 .013
Caudal Middle Frontal 17.26 (3.44) 17.98 (3.30) 0.18 .67 .002
Basal Ganglia 25.46 (2.44) 25.02 (3.07) 2.38 .13 .030
Cerebellum 124.97 (13.34) 127.55 (14.38) 0.01 .92 <.001

Note. ROI volumes combine left and right hemisphere volumes for each ROI structure. ROI units are measured in centimeters cubed. Basal Ganglia comprised the caudate, putamen, and pallidum volumes. ρη2 = partial eta squared. Partial eta squared is the default effect size measure reported in SPSS. If you have only one predictor variable, then partial eta squared is equivalent to eta squared. TD = typically-developing; ASD = Autism Spectrum Disorder.
