Variables and Cut-Off Criteria for Each Measure in the Risk Score Model

Risk Score Variables	Description	Included Measures	Variable Cut-Off Value*
Dysmorphology 1	Physical measurements consistent with a diagnosis of FAS	Palpebral fissure length percentile ≤10 percentile, philtrum lipometer score >3, vermillion Border lipometer score >3	>0 criteria
Dysmorphology 2	Physical deficits associated with prenatal alcohol exposure	Incomplete extension of digits, Ptosis	>0 criteria
VABS	Parent-reported adaptive functioning skills	Socialization, Communication, Daily Living Skills	>1 domain with standard scores <86
CBCL	Parent-reported behavior concerns	Somatic Complaints, Social Problems, Attention Problems, Rule Breaking Behavior, Aggressive Behavior	>0 subscales with a T-score >65

^*Subjects were assigned a score of 1 for each variable that exceeded the cutoff. Variables were weighed in the final risk score as follows: Risk Score = 1(Dysmorphology 1) + 1(Dysmorphology 2) + 2(VABS) + 1(CBCL).
