Figure 2.

Partial correlation graphs (plotted with standardized residuals) shows significant relationships between (A) resting state connectivity between left (L) and right (R) primary motor cortex (M1) and the Upper Extremity Fugl-Meyer (UE-FM) score, R² = 0.55; (B) fractional anisotropy (FA) in the transcallosal tract connecting left and right primary motor cortex (M1–M1) and the UE-FM score, R² = 0.48; (C) radial diffusivity (L2L3) in the transcallosal M1–M1 tract and the UE-FM score,R² = 0.55.
