Note. n = 203. Edu = Education; HC = Head Circumference; Exp = Experimenter; GA = Gestational Age. The pattern of associations for maternal reports of cigarette use per day in each trimester was similar to that of the maternal report of average cigarettes per day across the entire pregnancy. As such the average cigarettes per day across the entire pregnancy was retained as it was more parsimonious.
