Table 3.
Multiple linear regression model between the level of urinary 8-OHdG and incorporated concentration of arsenic and chromium (n = 142).
| Component model | Model parameter (SE) | Significance (p-value) | Explained variance (%) |
|---|---|---|---|
| Maternal education (< senior high school vs. > senior high school) | 2.8 (1.4) | 0.05 | 34.7 |
| Parental smoking status (yes vs. no) | 1.0 (1.4) | 0.47 | 2.2 |
| Allergic rhinitis (yes vs. no) | −3.0 (1.6) | 0.05 | 24.1 |
| Adjusted urinary arsenic (high vs. low)a | 1.9 (1.4) | 0.18 | 17.5 |
| Adjusted urinary chromium (high vs. low)a | 3.0 (1.4) | 0.04 | 21.5 |

Cut points were determined according to medians (arsenic, 7.7 μg/g creatinine; chromium, 2.0 μg/g creatinine) of urinary creatinine-adjusted levels among all subjects.
