Table 2: Medians, means (μ) and standard deviations (sd) of phthalate metabolite concentration (ln-values) distributions. Means and standard deviations designated as μ_cohort, μ_TS, sd_cohort and sd_TS were obtained via iterative nonlinear least-squares (nls) regression. Means and standard deviations for the cohort (μ_Pop and sd_Pop) accounting for the daily variation (representing population variance only) were calculated from μ and sd-values obtained of the cohort (representing population plus daily variance) and the sd-value of the longitudinal study cohort (sd_TS, representing daily variance only) as described in Materials and Methods.
