Statistical models were corrected for population stratification (first four principal components), age, sex, scanner device, handedness, intracranial volume, parental education and family income.

*Survives Bonferroni correction for multiple testing (p<0.05/16=3.13×10⁻³).

†Structure not part of the canonical cortical reading network.
