Fig. 7From: Digital quantification of p16-positive foci in fibrotic interstitial lung disease is associated with a phenotype of idiopathic pulmonary fibrosis with reduced survivalKaplan–Meier survival analysis grouped by p16-positive foci. A LTx-free survival was significantly worse in all ILD patients (p = 0.0015) with a high density of p16-positive foci. B LTx-free survival was significantly worse (p = 0.0058) in IPF patients with a high density of p16-positive fociBack to article page
