  • Note:—Mmtr = mean MTR; NPH, normalized peak height; Psite, peak site; Splen, splenium; FWM, frontal white matter; CSEM, centrum semiovale; Put, putamen; Caud, caudate; Tha; thalamus.

  • * Significant using FDR-adjusted P value. Spearman correlation coefficients for MSK; all others, Pearson correlation coefficients.
