Relationships of IQ and age with total brain volume (a, b), gray matter volume (c, d), and white matter volume (e, f) in the Yale sample, by diagnosis. Age negatively predicted TBV and GMV (a, c). IQ positively predicted all three measures (b, d, f). ASD status positively predicted all three measures
