Estimated weight distributions of urinary phthalate metabolites from 100 repetitions of weighted quantile sum (WQS) regression for (A) ADHD/compliance subscale and (B) hyperactivity/impulsivity subdomain. Boxes indicate 25th, 50th, and 75th percentiles, diamonds indicate mean, and whiskers indicate 10th and 90th percentiles of weights. The dashed line indicates the threshold (1/# of chemicals in the mixture). ADHD, attention-deficit/hyperactivity disorder; DEHP, di-2-ethylhexyl phthalate; MBzP, mono-benzyl phthalate; MCINP, mono-carboxy isononyl phthalate; MCIOP, mono-carboxy isooctyl phthalate; MCPP, mono (3-carboxypropyl) phthalate; MEP, monoethyl phthalate; MHPP, mono-2-heptyl phthalate; MIBP, mono-isobutyl phthalate; MNBP, mono-n-butyl phthalate
