Single pollutant models for PM2.5, PM10 and O3

Adj* B-coefficientAdj* 95% CIP value
PM2.5−10.45−10.21 to −10.72<0.001
PM10−10.42−10.21 to −10.67<0.001
O3−10.07−9.93 to −10.210.289

  • Adjusted relative changes (%) with their 95% CI in maximal fall in FEV1.

  • *Adjusted for humidity, temperature, age-squared, gender, BMI and atopic state.

  • BMI, body mass index; FEV1, forced expiratory volume in 1 s; O3, ozone; PM10, particulate matter < 10 µm; PM2.5, particulate matter < 2.5 µm.
