marginally significantp = 0.07
Although our previous study did not find any significant interactions between BPbCs and genotypes for any of the aforementioned three GST genes in relation to ASD status, using different conditional logistic regression (CLR) models, (all p for interaction between BPbCs and each of the GST genes > 0.49), a marginally significant interactive association of GSTP1 with a mixture of Pb, Hg, and Mn was detected ( p = 0.07) based on a negative association generalized weighted quantile sum (gWQS) model [ 40 ].
