The intraclass correlation coefficient was 0.09 (95% CI 0.01-0.44), indicating high within-participant variability relative to the between-person variation. Concordance of BPA quartile over time was low (31.7%) and was unrelated to demographic, behavioral, or dietary factors. A single, or even several, measurements of BPA may not adequately classify long-term exposure in human studies.<p> 2022-02-21T22:48:57.408-06:00 Within-person variability of urinary bisphenol-A in postmenopausal women 12347 Cancer document-rn7015 19274 public 10.1016/j.envres.2014.09.016
