Additional file 3: of Ambient PM2.5 and risk of emergency room visits for myocardial infarction: impact of regional PM2.5 oxidative potential: a case-crossover study

(Figure S1: Total sampling days for regional oxidative potential (OP) at each site (2012–2013). Values below the 10th percentile (30 days, indicated by the red vertical line) were excluded for sensitivity analyses; Figure S2: Regional estimates of glutathione (OPGSH) and ascorbate (OPAA)-related oxidative potential in Ontario, Canada (2012–2013); Figure S3: Distribution of daily PM2.5 mass concentrations across quartiles of glutathione-related oxidative potential (OPGSH); Figure S4: Ambient PM2.5, PM2.5 oxidative burden and emergency room visits for myocardial infarction: sensitivity analyses excluding sites with less than 1-month of oxidative potential data; Figure S5: Concentration response plots (using cubic splines with 4 knots) for NO2, O3, and Ox and risk of emergency room visits for myocardial infarction; Figure S6: Concentration response plots for PM2.5 and risk of emergency room visits for myocardial infarction above the 90th percentile of OPGSH and below the 50th percentile using cubic splines with 4 knots).
