Effect estimates are summarized as percent changes in outcome measures per IQR increase in PM2.5 (4.5 μg/m3), NO2 (9.5 ppb), and O3 (5.0 ppb) concentrations. All models were adjusted for age at baseline, follow-up time, race/ethnicity, study site, education, financial hardship, smoking, exposure to secondhand smoke, alcohol drinking, physical activity, total energy intake, and menopausal status. Bold font indicates P < 0.05.
