Fig. 6.

Scatter plot by treatment groups and PPA variants for change (after minus before) of absolute letter accuracy in % against change in connectivity for the IFG_triangularis_L: ITG_L pair. Variants are color-coded as red for nonfluent, green for semantic and blue for logopenic. Treatment assignments are coded as circles for tDCS and triangles for Sham. Fitted lines and pointwise confidence bands are plotted for each variant with the corresponding coded color and for all patients with the dot-dashed line and the color black. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
