Reasons and Number of Candidate Pharyngeal Acid Reflux Episodes That Do Not Fulfill the Definition of Hypopharyngeal Multichannel Intraluminal Impedance-pH-proven Pharyngeal Acid Reflux Episodes by Experts’ Consensus Reviews
| Post-PAR re-swallows of acidic refluxate | 8 |
| Post-PAR episode pH artifact | 1 |
| Post-esophageal-reflux reflexive swallows with acidic liquid | 2 |
| Equivocal candidate PAR episode | 1 |
| Full column reflux along with air trapped in pharyngeal impedance channels | 6 |
| Full column reflux along with pharyngeal nadir impedance greater than 1200 Ω | 3 |
PAR, pharyngeal acid reflux.
