Table 4.

Correlations between the independent variables of age, sex, ADOS-2 Module, ADOS-2 Calibrated Severity Score (CSS), CARS-2 score, and the VABS-2 communication (CD) and socialization domain (SD).

	Age	Sex	ADOS-2 module	ADOS-2 CSS	CARS-2	VABS-2 CD	VABS-2 SD
Age	1	−0.09	0.09	0.09	0.10	−0.21	−0.30
Sex		1	n/a	−0.20	−0.02	−0.22	0.03
ADOS-2 module			1	−0.11	−0.34*	0.60**	0.45*
ADOS-2 CSS				1	0.40**	−0.40*	−0.45*
CARS-2					1	−0.30	−0.23
VABS-2 CD						1	0.58**
VABS-2 SD							1

The correlations are Kendall's Tau-b correlations, except for correlations with sex, which are point-biserial correlations.

^*Correlation is significant at the 0.05 level (2-tailed).
