The role of cigarette smoking-derived pollutants in the risk of mortality in idiopathic pulmonary fibrosis

We thank T. Yasuma and co-workers for their valuable comments on our paper describing the association between individual-level long-term concentrations of air pollutants at the residential addresses of patients with idiopathic pulmonary fibrosis (IPF) and mortality among them [1]. We agree that the release of nitrogen dioxide (NO2) or particulate matter in cigarette smoke is one of the considerations in interpreting our results. Thus, we stratified all patients into ever- and non-smokers according to their smoking status and analysed the effect of air pollutants on mortality risk in these patients using our health analysis models that included different sets of confounders (figure 1).
