We read with interest the study by Abe et al on the clinical utility of nintedanib in patients with severe idiopathic pulmonary fibrosis (IPF).1 Based on the retrospective follow-up of 51 patients, the authors concluded that the survival benefit from nintedanib is reduced among patients with severe IPF (n=17) compared with those with mild-to-moderate IPF (n=34), but that the prognosis for patients with severe IPF is significantly better in those who remain on nintedanib for more than 3 months.
In our opinion, the study design does not allow conclusions to be drawn about the treatment effect of nintedanib on survival in patients with severe versus mild-tomoderate IPF.
