a
P values are reported for white matter and gray matter compartments, as well as for additional ROIs with significant effects. Interaction terms indicate longitudinal susceptibility variations of one group relative to the other.
b
Statistical significance (P < .05).
c
Significant after multiple-comparison correction.
