↵3-150 Adjusted for age, sex, employment grade, ethnicity, smoking, alcohol, body mass index, month, minimum daily temperature and relative humidity.
↵3-151 Differences (%), SEs, and odds ratios for an increase in concentration of pollutants from 10th to 90th percentile (for black smoke 18 μg/m³, PM₁₀ 33.1 μg/m³, SO₂ 23.2 μg/m³, CO 1.6 mg/m³, NO₂ 61.7 μg/m3, and O₃ 46.9 μg/m³).
↵3-152 Odds ratios for having fibrinogen above 3.19 g/l (highest 10%).
