Spearman correlations (p values) between participant characteristics and effect sizes (ES).

Variable	Treated items		Untreated items
	Treatment phase ES	Follow-up phase ES	Treatment phase ES	Follow-up phase ES
MPO	.094 (.662)	–.181 (.407)	–.234 (.282)	–.262 (.240)
AOS severity	.186 (.384)	.410 (.052)	.528 (.010) **	.438 (.041) *
WAB AQ	–.226 (.228)	–.517 (.012) *	–.482 (.020) *	–.466 (.029) *
Age (years)	–.278 (.189)	.080 (.716)	.140 (.523)	.099 (.661)

Note. Apraxia of speech (AOS) severity is based on a numeric scale ranging from 1 (mild) to 5 (severe). MPO = months postonset of stroke; WAB AQ = Western Aphasia Battery Aphasia Quotient.

^*Correlation is significant at the .05 level (two tailed).
