Figure 2. Mean Change in Perfluoroalkyl and Polyfluoroalkyl Substances From Baseline to Week 52.

Figure 2.

A, Mean change in perfluorooctane sulfonate (PFOS) level from baseline to week 52. B, Mean change in perfluorohexane sulfonic acid (PFHxS) level from baseline to week 52. Error bars indicate the SEM. Change in the observation group was not significant for either outcome (P = .96 for PFOS and P = .06 for PFHxS); change in the blood donation group was significant for PFOS (P < .001) but not for PFHxS (P = .54); and change in the plasma donation group was significant for both outcomes (all P < .001).
