From: Bolus transit of upper esophageal sphincter on high-resolution impedance manometry study correlate with the laryngopharyngeal reflux symptoms

Figure 3

(A) The ROC analysis indicated that a upper esophageal sphincter impedance integral (UESII) cutoff of 2900 Ω s cm achieved the best differentiation between subjects with reflux symptom index (RSI) score > 13 and others with RSI score ≦ 13. (B) A subject with RSI score = 0 had the impedance value of 2418 Ω above upper esophageal sphincter immediate after 5 mL saline liquid swallow. (C) A subject with RSI score = 42 had the impedance value of 1794 Ω above upper esophageal sphincter immediate after 5 mL saline liquid swallow.
