Two-pollutant model with PM2.5 and PM10
| Adj* B-coefficient | Adj* 95% CI | P value | |
| PM2.5 | −9.38 | −8.05 to −10.38 | 0.163 |
| PM10 | −11.27 | −10.07 to −12.59 | 0.036 |
Adjusted relative changes (%) with their 95% CI in maximal fall in FEV1
*Adjusted for humidity, temperature, age-squared, gender, BMI-squared and atopic state.
BMI, body mass index; FEV1, forced expiratory volume in 1 s; PM10, particulate matter < 10 µm; PM2.5, particulate matter < 2.5 µm.
