Concordance Rates of Diagnosing Candidate Pharyngeal Acid Reflux and Hypopharyngeal Multichannel Intraluminal Impedance-pH-proven Pharyngeal Acid Reflux Episodes Between 2 Independent Observers

HMII-pH measurements Concordance rates between 2 observers (%)
Candidate PAR episodes 88.2% (105/119)
Impedance
Full column reflux 98.9% (94/95)
Pharyngeal reflux 92.3% (84/91)
HMII-pH-proven PAR episodes 95.4% (83/87)

PAR, pharyngeal acid reflux; HMII-pH, hypopharyngeal multichannel intraluminal impedance-pH.
