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)

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
