Fig. 2From: Medium-long term prognosis prediction for idiopathic pulmonary fibrosis patients based on quantitative analysis of fibrotic lung volumeCorrelation between the survival time and patient characteristics. Graphs show that age (A) and FVC%pred (B) do not correlate with the survival time. DLCO%pred (r2 = 0.1207, P = 0.0260) (C) and KCO%pred (r2 = 0.1247, P = 0.0321) (D) positively correlated with survival. The GAP index (E) negatively correlated with survival (r2 = 0.1092, P = 0.0267). The baseline CTFLV/TLV% (F) showed a strongly negative correlation with survival (r2 = 0.5916, P =  < 0.0001)Back to article page
