Associations of personal and community-level exposure to air pollutants with odds of worsening respiratory symptoms

Legend: Mixed-model analyses showing odds of worsening respiratory symptoms per interquartile range (IQR) difference in previous-day pollutant exposure. All models are adjusted for previous-day temperature, humidity, season, age, sex, race, height, weight, total pack-year smoking history, and education. Black: results for any respiratory symptom, red: results for breathing symptoms (breathlessness, wheeze, tightness of the chest), blue: results for bronchitis symptoms (cough, sputum color, sputum amount). Abbreviations: OR, odds ratio, PM2.5, fine particulate matter less than 2.5 μm in diameter; NO2, nitrogen dioxide; O3, ozone.
