Interferon gamma-1b does not improve survival for patients with idiopathic pulmonary fibrosis
Statistics from Altmetric.com
Idiopathic pulmonary fibrosis (IPF) is characterised by an insidious decline in pulmonary function, progressive worsening symptoms and death, with a median survival of 2–5 years from diagnosis. A methodologically limited meta-analysis has suggested that interferon γ-1b (IFNγ-1b) might improve survival.
To test this hypothesis, the INSPIRE study group conducted a double-blind trial, randomising 826 patients with IPF to receive IFNγ-1b …
