| Regression coefficienta (95% CI) | p-value | Regression coefficienta (95% CI) | p-value | Regression coefficienta (95% CI) | p-value | |
| Systolic BP in mmHg (mean difference) | –0.05 (–1.24, 1.14) | 0.932 | –0.09 (–1.26, 1.08) | 0.880 | –0.24 (–1.44, 0.95) | 0.690 |
| Diastolic BP in mmHg (mean difference) | –0.24 (–0.91, 0.43) | 0.487 | –0.31 (–1.00, 0.37) | 0.368 | –0.43 (–1.11, 0.26) | 0.222 |
| Mean arterial pressure in mmHg (mean difference) | –0.19 (–0.99, 0.62) | 0.652 | –0.24 (–1.04, 0.56) | 0.557 | –0.36 (–1.17, 0.45) | 0.384 |
| Pulse pressure in mmHg (mean difference) | 0.26 (–0.43, 0.96) | 0.457 | 0.26 (–0.40, 0.93) | 0.439 | 0.17 (–0.52, 0.86) | 0.630 |
| Urinary total protein (ratio of medians) | 0.90 (0.78, 1.04) | 0.154 | 0.89 (0.78, 1.03) | 0.114 | 0.89 (0.78, 1.02) | 0.100 |
Refers to difference in mean blood pressure of participants or ratio of medians of 24-hour urinary protein of participants between communities with access to managed aquifer recharge water and without access.
N = 1891 person-visits for managed aquifer recharge water access group and N = 695 person-visits for brackish groundwater group
Model 1: adjusted for visit only; Model 2: adjusted for visit, age, sex and body mass index; Model 3: adjusted for age, sex, body mass index, marital status, physical activity, smoking status, alcohol consumption, hours of sleep, religion, salt intake and wealth quintile.
