From: Ambient PM gross β-activity and glucose levels during pregnancy
Stratified analyses by median maternal age of 32 years comparing the change in glucose concentration by quartiles of PM gross β-activity. All models were adjusted for PM2.5, temperature, pre-pregnancy body mass index, 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
