Task: Answer Verification
Input (English): Question: Is pharyngeal pH alone reliable for the detection of pharyngeal reflux events : A study with oesophageal and pharyngeal pH-impedance monitoring?
Answer: This study demonstrates that pharyngeal pH alone is not reliable for the detection of pharyngeal reflux and that adding distal oesophageal pH analysis is not helpful. The only reliable analysis should take into account impedance patterns demonstrating the presence of pharyngeal reflux event preceded by a distal and proximal reflux event within the oesophagus.
Output (English): no
