Table 4.

For each participant, long-term exposure was estimated as the geometric mean of the concentrations in all monthly composite samples collected throughout the second and third trimesters of pregnancy. The distribution of these geometric mean concentrations in the organic and conventional groups is presented for all metabolites with less than 70% censored data.

Concentrations in the conventional group were significantly higher than in the organic group (Mann-Whitney U test, p=0.03).
