Racial disparities in the impact of airborne pollutant exposures on asthma exacerbations. Sample sizes are: N = 6379 African American patients; and N = 13,176 Caucasian patients. PM2.5 = particulate matter < 2.5-μm in diameter. Levels of PM2.5 exposure were binned in FHIR PIT using pandas qcut and expressed as ranges. X2 = 28.2841, P < 0.0001 for African Americans; X2 = 47.0133, P < 0.0001 for Caucasians
