“…Therefore, acid parameters intuitively drive symptom outcome from medical management, and it follows that the predictive value of testing subjects off antisecretory therapy would be higher compared with those on therapy, as the diagnostic yield is much higher off therapy. In recent years, baclofen, a gamma amino butyric acid B receptor agonist, has been implemented as an adjunct to reduce the frequency of reflux events to complement anti-secretory therapy (43)(44)(45). This agent could potentially augment medical management of reflux and improve symptomatic outcomes by reducing reflux events; however, baclofen was not utilized for medical management in our study cohort.…”
