Figure 1. Sensitivity Analysis of the Association between Exposure to Organic Carbon (OC) over the First Trimester (0–13 Weeks of Gestation) and Gestational Diabetes Mellitus.
The odds ratios were adjusted for exposure to OC over the 3 months before pregnancy and the second trimester, maternal age, season of conception, parity, smoking, alcohol drinking, prepregnancy body mass index, infertility treatment, past history of gestational diabetes, and total PM2.5 concentration over the first trimester. The error bars indicate 95% confidence intervals.
*We did not construct a multicomponent model that included the same carbon component (elemental carbon).
