Estimated mean percent change in AFC by urinary paraben concentration tertile based on the Poisson regression model.
| Paraben concentration (μg/L) | n | Estimated mean percent change in AFC (95% CI) | p-Value |
|---|---|---|---|
| MP | |||
| Tertile 3 (381–2,428) | 47 | –10.6 (–28.2, 11.2) | 0.31 |
| Tertile 2 (145–377) | 48 | –6.8 (–23.5, 13.7) | 0.49 |
| Tertile 1 (5.13–132) | 47 | 0 (Reference) | |
| ptrend | 0.31 | ||
| PP | |||
| Tertile 3 (87.8–727) | 47 | –16.3 (–30.8, 1.3) | 0.07 |
| Tertile 2 (26.3–81.8) | 48 | –5.0 (–23.7, 18.4) | 0.65 |
| Tertile 1 (< LOD–25.2) | 47 | 0 (Reference) | |
| ptrend | 0.07 | ||
| BP | |||
| Tertile 3 (5.44–177) | 48 | –2.0 (–21.0, 21.6) | 0.86 |
| Tertile 2 (0.75–5.12) | 47 | –4.8 (–22.5, 16.8) | 0.63 |
| Tertile 1 (< LOD–0.73) | 47 | 0 (Reference) | |
| ptrend | 0.86 | ||
| All model results were adjusted for age; paraben concentrations were SG-corrected. LODs were 1.0 μg/L for MP and 0.2 μg/L for PP and BP. | |||
