Data have been calculated in a unique multivariate analysis separately for each lag, taking into account simultaneously each pollutant variables.
No. of observations for 24-hour mean not including H2S: lag 0: 22,436; lag 1: 22,327; lag 2: 22,288; and lag 3:22,367. No. of observations for 24-hour mean including H2S: lag 0: 13,816; lag 1: 13,686; lag 2: 13,598; and lag 3: 13,650. No. of observations for 3-day mean not including H2S: lag 0: 21,913; lag 1: 21,755; lag 2: 21,617; and lag 3: 21,682. No. of observations for 3-day mean including H2S: lag 0: 13,816; lag 1: 13,686; lag 2: 13,598; and lag 3: 13,650.
The matched odds ratios (OR) and 95% confidence intervals (CI) for the dispensation of glyceryl trinitrate in Reykjavik, Iceland, associated with every 10 μg/m3 increase in NO2, O3, PM10, and H2S 24-hour mean and 3-day mean concentrations. Adjusted for each pollutant variable, temperature, and relative humidity.
