Correlation analysis of exposure and outcome variables for single volunteers per household.
Spearman’s ρ (P value) | ||||
---|---|---|---|---|
Drinking Water As<1 μg/L (n = 65) | Drinking Water As1–10 μg/L (n = 47) | Drinking Water As>10 μg/L (n = 15) | Full range(n = 127) | |
Drinking Water As vs Urinary Total As | 0.27 (P = 0.03) | 0.42 (P = 0.004) | 0.48 (P = 0.07) | 0.40 (P < 0.001) |
Drinking Water As vs U-AsIMM | 0.23 (P = 0.06) | 0.49 (P < 0.001) | 0.69 (P = 0.005) | 0.60 (P < 0.001) |
Drinking Water As vs Osmolality Adjusted U-AsIMM | 0.19 (P = 0.13) | 0.54 (P < 0.001) | 0.82 (P < 0.001) | 0.62 (P < 0.001) |
A strong correlation (bold font) is only observed for U-AsIMM (osmolality adjusted) for drinking water As >10 μg/L. One volunteer per household was chosen at random for inclusion in analyses.
