Paired sample t tests revealed a marginally significant decrease in AD in the multi-domain CogTr group (student’s t (16) = 2.066, two-tailed P = 0.055); conversely, no significant alteration was seen in the controls (student’s t (13) = −0.401, two-tailed P = 0.695).

showed a trendno p-value reported

Participants in the multi-domain group showed a trend of long-term decrease in axial diffusivity (AD) without significant change in fractional anisotropy (FA), mean diffusivity (MD) or radial diffusivity (RD), while those in the control group displayed a significant FA decrease, and an increase in MD and RD.
