Figure 7 is a dot graph, plotting Hexafluoropropylene oxide dimer acid, Perfluorododecanoic acid, Perfluorononanoic acid, Perfluorobutanoic acid, Perfluorohexanoic acid, Perfluorobutanesulfonic acid, Perfluorooctanoic acid, Perfluorohexane sulfonate, Perfluorooctane sulfonate (y-axis) across relative potency factor, ranging from 0.1 to 1 in increments of 0.9 and 1 to 10 in increments of 9 (x-axis). — The internal relative potencies of nine PFAS based on relative liver weight (circles), plotted on a log10-scale. The horizontal lines indicate the 90% confidence interval ranges. Perfluorooctanoic acid (PFOA) was used as index compound (i.e., relative potency factor $equals 1$ ). Note: HFPO-DA, hexafluoropropylene oxide-dimer acid; PFAS, per- and polyfluoroalkyl substances; PFBA, perfluorobutanoic acid; PFBS, perfluorobutane sulfonic acid; PFDoDA, perfluorododecanoic acid; PFHxA, perfluorohexanoic acid; PFHxS, perfluorohexane sulfonic acid; PFNA, perfluorononanoic acid; PFOA, perfluorooctanoic acid; PFOS, perfluorooctane sulfonic acid.
