All RRs were obtained by taking the lowest quartile as reference category. Random intercepts were applied at the level of the study areas in all models.
Model 1: unadjusted model including Lden road, aircraft, railway, and their truncation indicators.
Model 2: Model 1 + age, sex, educational level, neighbourhood socioeconomic index, smoking status and pack-years, consumption of alcohol, fruits and vegetables, and NO2.
Model 3: Model 2 + physical activity, body mass index and change in body mass index.
Model 4: Model 3 + traffic noise annoyance.
Model 5: Model 3 + green space.
