Where < 0.01 is noted, this means the concentration was below the limit of quantification. Emboldened and shaded p values indicate statistical significance between seropositive and seronegative individuals,, for models containing raw or log-transformed PFAS concentrations. Where a value is recorded as NA, this compound was not detected in the species. When p values were adjusted using a Benjamini–Hochberg correction, no significant effects of pollution on AIV serostatus were found.
