Association of six major air pollutants with ERVs and hospital admissions for asthma in overall and sensitivity analyses.

<p>Abbreviations: PAF, population attributable fraction; PM₁₀, particulate matter of ≤10 μm; PM_2.5, particulate matter of ≤2.5 μm; RR, relative risk</p><p>The PAF was calculated by {PAF = P[(RR−1)/P(RR−1)+1]}, where P indicates prevalence of exposure to air pollution in the population which was estimated as 100%.</p><p>Association of six major air pollutants with ERVs and hospital admissions for asthma in overall and sensitivity analyses.
