Cumulative percent change (95% confidence interval)a in number of deaths, of lag 0–30 days, associated with air pollutant levels from an unconstrained model.b
| Deaths | Percent change (95% confidence interval) | ||
|---|---|---|---|
| PM10 | NO2 | CO | |
| Nonaccidental | –0.03 (–0.77, 0.71) | 0.32 (–0.51, 1.16) | –1.40 (–3.24, 0.48) |
| Circulatory | –0.98 (–2.10, 0.16) | –1.30 (–2.64, 0.05) | –3.91 (–6.78, –0.94) |
| Cerebrovascular | 0.45 (–1.68, 2.63) | –0.40 (–2.75, 2.00) | 1.05 (–4.16, 6.54) |
| Respiratory | 2.82 (0.97, 4.71) | 3.02 (0.95, 5.24) | 3.31 (–1.26, 8.09) |
| Chronic respiratory | 2.04 (–1.07, 5.24) | 0.98 (–2.49, 4.56) | 2.72 (–4.74, 1.08) |
| Cancer | 1.98 (0.57, 3.41) | 2.53 (0.83, 4.26) | 3.15 (–0.70, 7.15) |
| Notes: CO, carbon monoxide; NO2, nitrogen dioxide; PM10, particulate matter smaller than 10 μm. aAssociated with a 10-μg/m3 increase in PM10 and NO2 and with a 1-ppm increase in CO. bResults from an unconstrained Poisson generalized additive distributed lag model using cumulative lag structures of lags 0–10, 0–20, and 0–30 days for PM10, NO2, and CO, adjusted by trend, seasonality, temperature, relative humidity, weekdays, and holidays. | |||
