Within-Individual Correlations Between Exposures

Correlations were computed using Spearman rank correlation test (all input values were 0s and 1s) with the subset of exposures for which we recorded cases of autism spectrum disorders (ASD) among exposed individuals. Exposures enclosed within red squares were fully correlated with each other and therefore analyzed as a single factor. ADR indicates adrenergic receptor; FAAH, fatty acid amide hydrolase; GABA, ϒ-aminobutyric acid; GluR, glutamate receptor; mAChR, muscarinic acetylcholine receptor; nAChR, neuronal nicotinic acetylcholine receptor; NMDAR, N-methyl-D-aspartate receptor; RI, reuptake inhibitor; and VAT, vesicular amine transporter.
