Participant Flow

Subjects were enrolled at 104 sites in the United States from 07 January 2006 to 25 June 2008.

At screening, subjects completed a Patient Assessment of Upper Gastrointestinal Disorders Quality-of-Life Index (PAGI-QOL) and Patient Assessment of Upper Gastrointestinal Disorders-Symptom Severity Index (PAGI-SYM) questionnaires before enrollment in Dexlansoprazole Modified Release (MR) 60 mg or 90 mg once daily (QD) treatment groups.

Mean overall composite symptom-severity score changes were computed in response to 20 questions, each scored 0 (no symptoms) to 5 (most severe symptoms). Negative changes from baseline indicate improvement in symptoms (decrease in severity).
