Descriptive Statistics for Language Outcome and Predictor Variables

	Diagnostic group means			Diagnostic effect
Variable	Autism	Down	Typical	pη²	p
Initial CDI	113_b	40_a	70_ab	.06	(.063)
Supported SI	15_b	7.2_a	20_b	.23	(.001)
Coordinated SI	3.3_a	5.6_a	9.8_b	.19	(.001)
PPVT-III	73_b	56_a	99_c	.49	(.001)
EVT	78_b	58_a	103_c	.50	(.001)

Note. Effect sizes are from diagnostic group analyses of variance; n = 18, 22, and 55 for all AU, DS, and TD variables, respectively, except TD PPVT-III (n = 53) and TD EVT (n = 54). For each variable, means that share a common subscript did not differ significantly, p < .05, per a Tukey post hoc test.
