Age-stratified results for juvenile-stratified (top) and adult-stratified (bottom) adjusted parametric quantile regression models testing for percent differences in cortisol (10 nM) across PFAS tertiles. Juveniles were defined as female dolphins <7 years old and male dolphins <10 years old. Adult dolphins were defined as female dolphins ≥7 years old and male dolphins ≥10 years old. Models were adjusted for location, year, sex, and age at time of sample collection. Shapes indicate which class the modeled PFAS belongs to a filled circle = PFCA class, a filled square = PFSA class and an empty shape = the sum of a single class or both classes combined (i.e., empty circle = ΣPFCA, empty square = ΣPFSA, and empty triangle = Σall PFAS combined). Regression coefficients, 95% confidence intervals, and n for each model is listed in Table S6.
