Fig. 2From: The impact of respiratory reactance in oscillometry on survival in patients with idiopathic pulmonary fibrosisThe time-dependent ROC curves of each Xrs index and %FVC for the 3-year survival prediction. X5 In (a), Fres In (b), ALX In (c), and %FVC (d). ALX, low-frequency reactance area; Fres, resonant frequency; %FVC, forced vital capacity (% predicted); In, inspiratory phase; X5, reactance at 5 Hz; Xrs, respiratory reactanceBack to article page
