Fig. 2: PFAS and OH-PCB concentration versus age.
From: Associations of PFAS and OH-PCBs with risk of multiple sclerosis onset and disability worsening
A PFHpS, B PFOA, C PFOS, and D 4-OH-CB187 concentration versus age in individuals with MS and HC subjects. Plots contain concentration distribution for individuals with MS (filled shape) (n = 907) and HC subjects (empty shape) (n = 907), where males are represented by triangles and females by circles. Imputed concentrations are shown in gray, and measured concentrations in black. The loess regression curve, including 95% confidence band, has been fitted separately for males (blue solid line) and females (pink dashed line), excluding the imputed concentrations (gray circles and triangles). Source data are provided as a Source Data file.
