  • Note:—NCV indicates normalized cortical volume; NWMV, normalized white matter volume; T2-LV, T2 lesion volume.

  • Regression analysis was adjusted for the effects of age and sex. All P values were corrected for multiple comparisons using Benjamini-Hochberg correction.

  • * indicates significant P values (P < .05) after correction.
