Figure 2.

Inter-correlation analyses among mean free water (FW) and FW-corrected mean diffusivity values of five tracts of interest and white matter reference regions, small vessel disease MRI markers and brain atrophy. (A) Correlation coefficients of FW-corrected mean diffusivity (MD-t) values. (B) Correlation coefficients of FW values. White matter hyperintensities (WMH) and brain volumes were normalized to intracranial volumes; all numbers within squares represent correlation coefficients (P-corrected <0.05), blank means no statistically significant results (P-corrected >0.05). CMBs = cerebral microbleeds.
