Association between current well Asa level and percent difference in endothelial function as measured by reactive hyperemia index (RHI), adjusted for covariatesb (N=199).
| N | % difference in RHI (95% CI)b | p-value | p-trend | |
|---|---|---|---|---|
| Blue (<10 μg/L) | 38 | Ref. | -- | 0.13 |
| Green (10–50 μg/L) | 70 | −3.82 (−13.30, 6.66) | 0.45 | |
| Red (>50 μg/L) | 91 | −7.32 (−16.18, 2.43) | 0.14 |
a
Current well level was imputed as most recent recalled well color if current well color was unknown at time of assessment.
b
Model adjusted for participant sex, age, education level and weight at time of assessment and maternal education and land ownership. Percent difference in RHI estimated by back-transformation of beta estimate of natural log transformed reactive hyperemia index (lnRHI). Missing maternal education and land ownership for one participant reduced sample size to N=199.
