Results from nested linear models with WQS and discovered interaction indicators (cutoff set at 75th percentile) and the WQS chemical mixture. In the top three models, the WQS chemical mixture and the two interaction indicators were used in separate models. Both interaction indicators were adjusted with the WQS chemical mixture in the following two models. In the last model, interaction indicators and the WQS chemical mixture were put in the same model. All models were adjusted for the covariates listed above.
