TABLE 4.
Morphometric measurements of the corpus callosum (CC) between neurotypical boys and boys with autism spectrum disorder (ASD).
| Measurement | Neurotypical (n = 28) | ASD (n = 21) |
| Age (y) | 5.4 ± 2.1 | 7.6 ± 1.9 |
| CC length (mm) | 61.5 ± 4.0 | 63.9 ± 6.3 |
| CC total area (mm2) | 455.3 ± 83.8 | 381.9 ± 80.2** |
| CC thickness (mm) | ||
| Genu | 9.0 ± 1.5 | 7.8 ± 1.3** |
| Body | 5.2 ± 1.1 | 4.3 ± 1.0** |
| Splenium | 13.8 ± 2.7 | 9.2 ± 2.1** |
Values are represented as the mean ± standard deviation (SD). ** P < 0.01 compared to neurotypical boys in the same row (independent t-tests).
