Table 2 Percentage of all samples above limit of detection as well as concentrations of PFHxS, PFOA, PFNA, total-PFOS, PFDA, PFUnDA (ng/mL) in maternal serum from visit 1 and partner serum presented as median (5–95% percentiles), and range [minimum and maximum concentrations]. Percentage difference between (geometric means of) paternal and maternal PFAS concentrations, and correlations of (log-transformed) PFAS concentrations within households, both presented with 95% confidence intervals
