Proportion of studies reporting treatment-related brain changes in a specific brain region of the left hemisphere, relative to the total number of studies providing this type of intervention. The number of studies (#) and patients with aphasia (n) per type of intervention is reported in the figure legend. SFG/MFG/IFG = superior/middle/inferior frontal gyrus, IFS = inferior frontal sulcus, oper = opercular, tri = triangular, orb = orbital, med = medial, SMA = supplementary motor area, IPG/SPG = inferior/superior parietal gyrus, SPL = superior parietal lobule, SMG = supramarginal gyrus, AG = angular gyrus, STG/MTG/ITG = superior/middle/inferior temporal gyrus, SOG/MOG/IOG = superior/middle/inferior occipital gyrus, HC = hippocampus, PHCG = parahippocampal gyrus. Anatomical labels other than those included in the AAL-VOI atlas used by the included studies that did not report standard brain coordinates are IFS and SPL.
