Figure 2. Results of the Sensitivity Analysis Including Percentage of Neutrophils and White Blood Cell Count.

Estimates are shown with 95% CIs (error bars) for the relative percentage change in histone H3 methylation for a 5-μg/m³ increment in exposure for particulate matter with a diameter less than 2.5 μm (PM_2.5) and nitrogen dioxide (NO₂), and a 0.5-μg/m³ increment in exposure to black carbon (BC). Estimates were adjusted for maternal education level, maternal smoking, maternal age , maternal prepregnancy BMI, parity, newborn sex, gestational age, season of delivery, trimester-specific apparent temperature, white blood cell count, and percentage of neutrophils. H3K4me3 indicates trimethylated H3 lysine 4; H3K36me3, trimethylated H3 lysine 36.
