Developmental trajectory of hemoglobin is moderated by neighborhood socioeconomic status. To visualize the significant interaction between age and neighborhood SES (both continuous variables) for males (left) and females (right), fitted lines are displayed that depict the relationship between age and hemoglobin at the top (higher SES, orange lines) and bottom (lower SES, purple lines) deciles of the range for neighborhood SES. Solid lines smooth fits from generalized additive models. Shaded areas reflect 95% CIs of the fit. Density plots represent the distributions of the plotted variables. SES, socioeconomic status.
