Cox proportional hazards regression, withsite specific baseline hazards and clustered on caregiver, was used to estimate hazard ratios, adjustment included substance caregiver type, sex, Hispanic ethnicity, race, baseline substance use (other than the outcome), and age. Odds ratios are displayed per test points (pts) for continuous variables, means are displayed on the raw scale. CCTT=Children Color Trials Test; BREIF=Behavior Rating Inventory of Executive Function; GEC= Global Executive Composite, BRI=Behavioral regulation index; MI=Metacognition index; WISC=Wechsler intelligence scale for children; FSIQ=Full scale intelligence quotient.
