Figure 4.

Distributions of cortical thickness for girls (pink) and boys (blue) separately at each Time point. At Time 1, average cortical thickness was 3.26 for girls, and 3.38 for boys; at Time 2, average cortical thickness was 3.31 for girls, and 3.28 for boys; at Time 3, average cortical thickness was 3.2 for girls, and 3.2 for boys; and finally at Time 4, average cortical thickness was 3.15 for girls, and 3.16 for boys. None of the differences in CT values between girls and boys were significant.
