Adjusted ORs and 95% CIs for the incidence of AE-IPF with different monthly lag periods. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) showing the increased risk of acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) associated with a 10-unit increase in the levels of sulfur dioxide (SO2), nitric oxide (NO), nitrogen dioxide (NO2), nitrogen oxides (NOX), carbon monoxide (CO), ozone (O3), particulate matter < 2.5 µm (PM2.5) and particulate matter < 10 µm (PM10) with different monthly lag periods. The adjusted ORs were estimated using multilevel mixed-effects logistic regression models, adjusting for temperature, humidity, age, sex, smoking status (pack-years) and percentage of the predicted value of forced vital capacity and diffusing capacity of the lung for carbon monoxide, and neighbourhood-level factors
