Fig. 3

The moderation of maternal prenatal smoking and infant ADHD T-score by TL attrition. A scatter plot of infant TL attrition from 4 to 18 months of life (i.e., ∆TL = 4-month TL–18- month TL) against ADHD T-score is presented by maternal prenatal smoking groups. Infants whose mothers reported smoking during pregnancy are represented by black circles and infants of nonsmokers are represented by grey-outlined white circles. Linear trend lines are fitted to each group to visualize the relation between TL attrition and ADHD T-score
