Repetitive behavior profiles: Consistency across autism spectrum disorder cohorts and divergence from Prader–Willi syndrome

Table 4 Comparison of RBS-R scores across PWS group with SCQ <15, PWS group with SCQ ≥15 and ASD sample after controlling for covariates (age and gender)

	PWS with SCQ < 15 (L) (n = 32)	PWS with SCQ ≥ 15 (H) (n = 12)	Combined ASD (n = 207)	GLM F_2,246	p	Post-hoc (p)

Only those with significant differences (p ≤ 0.001, presented in bold typeface) were listed in the post-hoc test column and Bonferroni’s test was used as a post-hoc procedure
L PWS group with lower total SCQ score (<15), H PWS group with higher total SCQ score (≥15), EMM (SE) estimated marginal means (standard error)
Significance for the post-hoc test was set as p < 0.05. *p < 0.05, **p < 0.01, ***p < 0.001
