Note: WJ-R = Woodcock-Johnson Psycho-Educational Battery–Revised; WISC = Wechsler Intelligence Scale for Children–Third Edition. Models estimated using child-level weight. WISC-Digit Scores not shown because this test did not adjust for child age. Multivariate models adjust for age-related differences in children’s Digit Scores.
