  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Results limited to patients without overt Gastroesophageal reflux disease(GERD). Did not conduct on-treatment potential hydrogen(pH) probe studies to confirm treatment effect. Protein-pump inhibitors(PPI) dose may not induce maximal acid suppression.
