Mean Nocturnal Baseline Impedance (MNBI) Provides Evidence for Standardized Management Algorithms of Nonacid Gastroesophageal Reflux-Induced Chronic Cough

<div>The AUC<sub>ROC</sub> of proximal MNBI and weakly acid reflux for predicting the efficacy of standard antireflux therapy. (a) When proximal MNBI was used to predict the efficacy of standard antireflux therapy, the AUC was 0.789 (95% confidence interval (CI): 0.590–0.921), with a moderately good predictive ability. When 2140Ω was adopted as a cutoff point, the Youden index was the highest (0.629). (b) When weakly acid reflux was used as a predictor, the AUC was 0.761 (95% CI: 0.636–0.860), with a moderately good predictive ability. When 45 was adopted as a cutoff point, the Youden index was the highest (0.401).</div>
