Logistic regression models for self-sucking presence (‘self-stimulation’ subcategory) ¹.

Independent Variables	Unadjusted Odds Ratio and p-Value	Adjusted Odds Ratio *	95% CI *	p-Value *	Positively and Significantly Predicts Self-Sucking? * (Result the Same if Age, Sex and Scanning Level not Controlled for?)
Self-clasping presence vs. absence	2.52 (<0.001)	2.55	0.45–14.33	0.144	No (Unadjusted relationship is positive and significant)
Eye-poking presence vs. absence	1.48 (0.166)	2.24	0.08–64.81	0.319	No (Unadjusted relationship is also positive and non-significant)
Hair-plucking presence vs. absence 2	0.09 (0.999)	0.59	0.12–2.80	0747	No (Unadjusted relationship is also negative)

* Adjusted for sex, age, and scanning level. ¹ One-tailed p-values are reported here. ² Interaction not tested due to insufficient observations.
