Additional file 2: of Serum AGE/RAGEs as potential biomarker in idiopathic pulmonary fibrosis

Correlation between RAGE, AGE and PFT. AGE: advanced glycation end-product, cHP: chronic hypersensitivity pneumonitis, DLCO: diffusing capacity for carbon monoxide, fNSIP: fibrotic non-specific interstitial pneumonia, FVC: forced vital capacity, IPF: idiopathic pulmonary fibrosis, r: correlation coefficient, R2: coefficient of determination, sRAGE: soluble receptor for advanced glycation end-products, TLC: Total lung capacity.
