Univariate associations between PFOS and PFHxS in office workers’ serum and PFOS in dust.
| Dust Analyte (ng/g) | n | lnPFOSa β (p-value) |
lnPFHxSa β (p-value) |
|---|---|---|---|
| PFOS | |||
| Office | 31 | -0.0035 (0.31) | -0.0052 (0.31) |
| Home | 30 | 0.0007 (0.69) | 0.0048 (0.03) |

Exponentiation of β = the multiplicative increase in PFC per unit change in predictor variable (e.g., β = 0.0013 is a 0.13% increase in serum PFC per ng/g increase in PFC dust concentration.
