Fetal alcohol spectrum disorder: neurodevelopmentally and behaviorally indistinguishable from other neurodevelopmental disorders

Table 4 Number of participants assigned to each subgroup and the classification function of the 2-class model in analysis 1

Group assignment; Classification function^a (%)	Children with FASD (n)	Typically developing control children (n)
Subgroup 1	20	4
Subgroup 2	1	33
Sensitivity (%)	95.2 (95% CI: 84.2–100.0)
Specificity (%)	89.2 (95% CI: 78.4–97.5)
PPV (%)	83.3 (95% CI: 66.7–96.2)
NPV (%)	97.1 (95% CI: 90.3–100.0)

CI Confidence Interval, FASD Fetal Alcohol Spectrum Disorder, n/a Not Applicable, NPV Negative Predictive Value, PPV Positive Predictive Value
^aAssuming subgroup 1 is reflective of the neurodevelopmental profile of FASD and subgroup 2 is reflective of typically developing control children
