Significant predictors, all χ²(df = 2–4, N = 48) > 16, all ps < .05, FDR-corrected for multiple comparisons, for each of the Western Aphasia Battery–Revised standard scores included PWA characteristics including lesion volume, apraxia of speech (AOS) severity, and age, as well as functional connectivity among regions of interest in the frontal, temporal, and parietal lobes and involving unilateral (right [R], left [L]) and bilateral (B) connections.

		Predictor	Aphasia Quotient	Spontaneous Speech	Content	Fluency	Auditory Comprehension	Repetition	Naming and Word Finding
		Lesion volume	Larger lesion = lower score	Larger lesion = lower score	Larger lesion = lower score	Larger lesion = lower score			Larger lesion = lower score
		AOS severity	More severe AOS = lower score		More severe AOS = lower score			More severe AOS = lower score	More severe AOS = lower score
		Age			Older = better score
Connection location
Frontal	L	lIFG-lMFG							Weaker FC = lower score
Frontotemporal	R	rpMTG-rIFG	Weaker FC = lower score						Weaker FC = lower score
Temporal	B	lFusi-riITG			Stronger FC = higher score
Temporoparietal	L	lAG-lsITG					Stronger FC = higher score
Parietal	B	lAG-rAG					Stronger FC = higher score

Note. FC = functional connectivity; l = left; r = right; IFG = inferior frontal gyrus; MFG = middle frontal gyrus; pMTG = posterior middle temporal gyrus; iITG = inferior inferior temporal gyrus; Fusi = fusiform gyrus; AG = angular gyrus; sITG = superior inferior temporal gyrus.
