p<0.05 difference between referent and comparison groups.
EGA = estimated gestational age. Maternal age represents the age at the indicated follow-up. Prenatal depression AUC = depression scores across pregnancy calculated as the area under the curve from the Beck Depression Inventory assessed multiple times throughout pregnancy. Maternal PDD, Alternate Caregiver PDD and child expressive language were assessed at the pre-school aged follow-up. PDD = maternal or caregiver-reported child pervasive developmental disorder as measured by the Child Behavior Checklist (CBCL).
