Percentage differences in hair tetraiodothyronine (T4) concentration per 2-SD increase in -transformed pollutant (continuous variable; blue circle symbol) concentration or detect vs. nondetect (binary variable; dark blue square) in (A) the multipollutant lasso model or (B) the subsequent multipollutant OLS model on the pollutants stably selected by the lasso model among 196 healthy Chinese women of reproductive age. Models were adjusted for age, body mass index, and city. Symbols in (B) represent average percentage differences and lines represent 95% CIs. Numerical values are reported in Excel Tables S6 and S8. Note: 3Me4NP, 3-methyl-4-nitrophenol; AM, amide herbicide; AZ, azole fungicide; CI, confidence interval; , 3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropanecarboxylic acid; DETP, diethylthiophosphate; DMP, dimethyl thiophosphate; HCH, hexachlorocyclohexane; Lasso, least absolute shrinkage and selection operator; OC, organochlorine; OLS, ordinary least squares; OP, organophosphate; PCP, pentachlorophenol; PY, pyrethroid; SD, standard deviation; TH, thiocarbamate herbicide; TR, triazine/triazone herbicide.
