Partial response plots for the peak bilirubin level with maternal exposed to PM2.5, SO2 and CO. The y-axis represents the marginal effects. The x-axis represents average concentrations of PM2.5 (a), SO2 (b) and CO (c). The dashed lines represent 95% CI. The vertical lines adjacent to the x-axis represent the frequency of the data
