↵a ICCs for 2D-SE and 3D-GE cortical thickness estimates using FreeSurfer are shown. The ICC values are grouped in 5 categories. Zero percent of the structures had almost perfect agreement, 1.4% had substantial agreement, 40% had a moderate agreement, 42.9% had fair agreement, and 15.7% had slight agreement.
