Attention scores. Although the plots show varying relationships by group, the interactions were not significant. In addition to the exposure group main effect, the main effect of age was significant; overall attention scores increased with age at assessment.

Figures 1–6 represent the scatterplots of estimated marginal means of significant NNNS summary variables plotted against the log-transformed age at infant assessment for each medication exposure group. A Loess curve was fit to the data to examine possible nonlinear relationships.
