Results were determined after removal of all case subjects rated as having no evidence of DP (severity rating of <1 from both raters) and all control subjects rated as having any DP (severity rating of ≥1 from either rater).
a
Age-standardized, neurodevelopmental test scores from the BSID-III.
b
Control subjects were used as the reference group. Values were adjusted for age (continuous), gender, and family SES10 (included as a continuous score).
