Author Correction: Forced oscillation technique in progressive pulmonary fibrosis in a single-center retrospective study

The original version of this Article contained errors where FOT values were referred to as measured values (in centimeter of water per liter per second) but are expressed in Z-scores.As a result, In the Abstract, "Compared to non-IPF stable ILDs (n = 96), PPF patients (n = 45) showed lower median resistance at 5 Hz (X rs5 ) values (during inspiratory phase: 0.31 versus -0.39 cmH2O/(L/sec), p = 0.019595)." now reads: "Compared to non-IPF stable ILDs (n = 94), PPF patients (n = 45) showed lower median reactance at 5 Hz (X rs5 ) values (during inspiratory phase: 0.31 versus -0.39 expressed as Z-scores, p = 0.019595)."In the Results, under the subheading 'Demographic, treatments and functional characteristics' , "In comparison to stable patients, PPF patients included less non-smoker (46 patients (49%) versus 15 patients (33%), p-value (p) < 0.001) (Table 1)." now reads: "In comparison to stable patients, PPF patients included less non-smoker (49 patients (52%) versus 13 patients (29%), p-value (p) < 0.05) (Table 1)."And "Compared to stable patients, PPF had statistically significantly lower FEV-1 (76 19 versus 85 16, p = 0.005), FVC (74 18 versus 87 16, p < 0.001), total lung capacity (TLC) (77 18 versus 92 20, p = 0.006) and DLCO (53 19 versus 70 22, p < 0.001) values." now reads: "Compared to stable patients, PPF had statistically significantly lower FEV-1 (76 19 versus 85 16, p = 0.005), FVC (74 18 versus 87 16, p < 0.001), total lung capacity (TLC) (77 18 versus 92 20, p = 0.006) and DLCO (53 19 versus 70 22, p < 0.0001) values."
