Exposure to air pollution and the onset of a myocardial infarction (MI) in the Strasbourg (France) Metropolitan Area, 2000–2007, base modela.

aAssociations observed for different lag times; excess odds ratios (eOR) are expressed as per cent (95% confidence interval) increase for i) a 1 µg/m3 increase in benzene concentrations; ii) a 10 µg/m3 in NO2, O3 and PM10 concentrations and iii) a 100 µg/m3 increase in CO concentrations. Adjusted for the previous day maximum atmospheric pressure, same day minimum temperature and influenza epidemics.
