(A,B) Diagnostic accuracy of the CII according to baseline values of FVC (A) and DLCO (B) by means of receiver-operating characteristic curve analysis. (C) Scatter plot of CII and DLCO values stratified according the presence of ILD. 0.1966 was the cut-off value obtained by analyzing the diagnostic accuracy of the CII (see Fig. 1, panel E). CII = computerized integrated index; FVC = forced vital capacity; DLCO = diffusing lung capacity for carbon oxide; ILD = interstitial lung disease; AUC = area under the curve; CI = confidence interval.
