Diagnostic accuracy of small-airway function variables combined with EOS in blood
We repeated the ROC analyses for spirometry measurements (FEF50%, FEF25%-75%, FEV1/FVC) combined with EOS (Table 6). The AUCs of the combined models were between 0.734 and 0.786, and all had NPV ≥ 85.08%. The AUCs of FEFs combined with EOS were higher in patients with chest tightness than in the population as a whole (0.815, 0.845, and 0.816, for FEF50%, FEF75%, and FEF25%-75%, respectively; Table 5).
