a positive trendP = 0.18
We found average Ktrans and kGad in WMHs were significantly correlated (linear regression) with the number of WMHs (Ktrans: β = 1.1 × 10 −5 , P = 0.02; kGad: β = 1.3 × 10 −3 , P = 0.02), and observed a positive trend between WMH kw and the number of WMHs (β = 1.2, P = 0.18).
