Association between the lag0, lag1 and the 2-day cumulative average of PM10, PMion, PMrest, PM2.5, soot and acute myocardial infarction hospitalisations in Gothenburg, Sweden (1985/1990*/2006*) − 2010) as percentage change in risk (%) and 95% confidence intervals during (A) the entire year, (B) warm period (April − September) and (C) cold period (October − March). Models adjusted for temperature, relative humidity and public holidays. Number of cases (n) used in the models is less than the original number due to missing exposure data. *PM10 and PMrest data from 1990 and PM2.5 data from 2006.
