6-minute walk distance as a predictor of outcome in idiopathic pulmonary fibrosis

From the authors: We thank M. Mura for reminding us of the study published in the European Respiratory Journal ( ERJ ) in 2012 that confirmed the increasing importance of the 6-min walk test (6MWT) in the evaluation and prediction of outcome in patients suffering from idiopathic pulmonary fibrosis (IPF) [1]. In this prospective study by Mura et al. [1], of factors that predicted survival in 70 patients with newly diagnosed IPF, the major 6MWT findings were that the 6-min walk distance (6MWD) % predicted, but not 6MWD defined as metres walked, was independently associated with 3-year survival, and …
