^aIndicate the thicker hemisphere and mean interhemispheric difference in mm.

^bIndicates the hemisphere in which the age effect is stronger.

^{c, e}For a male‐female comparison; a positive t‐score indicates male thicker than female.

^dFor a male‐female comparison; a positive t‐score indicates that the age effect is stronger for males than females.

^eSignificant at the α = 0.01 level (corrected for multiple comparisons).

^fSignificant at the α = 0.05 level (corrected for multiple comparisons).
