Total BPA geometric means, percentiles, and maximum concentrations in maternal and child urine samples
| Detection Frequency (% > LOD) | Urinary Total BPA (ng/mL) | ||||||
|---|---|---|---|---|---|---|---|
| GM (95% CI) | P25% | P50% | P75% | P95% | Max | ||
| Maternal (n = 98)a | 88.8 | 1.4 (0.5, 2.2) | 0.5 | 1.5 | 2.7 | 10.7 | 34.9 |
| Child (n= 77) b | 91.0 | 1.0 (0.6, 1.5) | 0.5 | 0.9 | 1.8 | 6.1 | 10.9 |
LOD limit of detection, GM geometric mean, 95% CI: confidence interval of GM, P25: 25th percentile; P50: 50th percentile; P75: 75th percentile; P95: 95th percentile. MAX: maximum concentrations
