LOESS graph of the adjusted associations between home proximity to the nearest greenhouse, with PNP and TCPy concentration. Each data point represents the adjusted least squares of ln(PNP) or ln(TCPy) concentration for 350 ranks of ln(home distance to the nearest greenhouse [m]). The models adjusted for age, height-for-age z-score, BMI-for-age z-score, race, gender, monthly income, parental education, living with an agricultural or flower worker. The blue line represents the LOESS line, while the shaded blue regions are the 95% confidence intervals for the LOESS line. For Fig. 1a, the β estimate is the percent difference of TCPY for a 50% greater home distance to the nearest greenhouses (β_{per 50% greater distance}) (see Table 2) For Fig. 1b, a 200 m reference line (equal to a y value of 5.3) is shown to to represent the cut-off point used in our stratified analysis (see Table 3), and the respective β_{per 50% greater distance} estimate for each strata is shown.
