From: Ambient PM gross β-activity and glucose levels during pregnancy
Change in glucose concentration for each quartile of PM gross β-activity concentration relative to the first quartile from the day of GCT (panel a), the week prior (panel b), the first trimester (panel c), and the second trimester (panel d). All models were adjusted for PM2.5, temperature, pre-pregnancy body mass index, maternal age, maternal race/ethnicity, maternal educational attainment, insurance status, median neighborhood income, median value of owner-occupied housing, and percent open space. The x-axis represents the quartile of PM gross β-activity, and the y-axis represents the change in glucose concentration in mg/dL. The error bars denote the 95% confidence intervals
