Figure 4: Model predictions for PCB 118 in liver (a) and fat lipids (b) for the nonperiodic dose scenario at the 50 μg/kg dose level. Data for all rats are shown (black triangles), and measurements for each rat at time of sacrifice have been shifted slightly on the 𝑥 -axis. Modeled results are the median and 95% confidence interval of 1000 model runs using parameters randomly sampled from the posterior distribution.
