Weblevels and the compound importance (%IncMSE) in our predictive model. For example, the high concentration of phthalates with low %IncMSE values indicated a weak effect on the prediction of gestational age. Together, these results suggest EDCs and EHs can accurately predict the gestational age on the basis of urine samples from pregnant women. 2.4.
