Age-adjusted intraclass correlation coefficients (ICCs, with 95% confidence intervals) of HOME Study children’s urinary BPA concentrations collected from 1–8 years of age (long- term, N=297, repeated samples=1,307) and ~2 weeks apart from 1–3 years of age (short-term, N=60, repeated samples=134).1
1Long-term ICCs derived from BPA concentrations in urine collected at 1, 2, 3, 4, 5, and 8 years of age. Short-term ICCs derived from BPA concentrations taken 2-weeks apart at 1, 2, and 3 years of age.
