Figure 4: Graphs showing patterns of metabolic changes during the course of cholesterol treatment. Graphs represent the average fold change (log2 scale) from controls for all masses contained within each of the four clusters identified in the HCA. Error bars represent standard deviations. a = p < 0.05 from control, b = p < 0.05 from week 4, c = p < 0.05 from week 8.
