Clusters exhibiting significant between-group differences independent of age on cortical gyrification. The effects are illustrated by a representative boxplot. Results were corrected for multiple comparisons using cluster analysis, p < 0.05, two-sided. There were no surviving clusters for cortical thickness, surface area, and cortical volume. The numeric labels indicate distinct clusters, and the corresponding information associated with each cluster can be found in the tables. Dark gray = sulci; light gray = gyri
