Association with IQ, controlling for sex (n = 164) after adjusting for other brain compartments

	Adjusting only for sex^*		Adjusting for sex and other brain volumes^†
Brain compartment	Slope^‡ (SE)	P value	Slope (SE)	P value
Grey matter	−2.67 (1.21)	.029	−1.05 (1.52)	.492
White matter	−3.36 (1.15)	.004	−2.50 (1.27)	.051
Cerebellum and brainstem	−5.11 (1.15)	<.001	−3.80 (1.56)	.016

Separate regression analyses for each brain volume, controlling for sex.

^†

A single multiple regression model with grey matter, white matter, cerebellum and brainstem, and sex as independent variables.

^‡

Slopes are scaled to reflect the difference in IQ associated with a 1-SD decrease in brain compartment volume.
