Inspiratory resonant frequency of forced oscillation technique as a predictor of the composite physiologic index in interstitial lung disease

Highlights • The usefulness of the forced oscillation technique in interstitial lung disease is unclear. • The composite physiologic index (CPI) is derived from FEV1, FVC, and diffusing capacity. • We assessed the relationship between the CPI and forced oscillatory parameters in interstitial pneumon...

Zusammenfassung:	Highlights • The usefulness of the forced oscillation technique in interstitial lung disease is unclear. • The composite physiologic index (CPI) is derived from FEV1, FVC, and diffusing capacity. • We assessed the relationship between the CPI and forced oscillatory parameters in interstitial pneumonia. • Inspiratory resonant frequency of forced oscillation technique was an independent predictor. • Fibrosis score was also an independent predictor of the CPI.
