The number of antacids consumed each day was
recorded in the daily symptom diary. Quality of life was
assessed using validated, self-administered questionnaires
at each study visit, after a training session at
the screening visit. The Quality of Life in Reflux and
Dyspepsia (QoLRAD)30 questionnaire assessed dimensions
of emotional distress, sleep, vitality, food/drink
habits, and physical/social functioning and the Gastrointestinal
Symptom Rating Scale (GSRS)31 assessed
dimensions of indigestion, diarrhoea, constipation,
abdominal pain and reflux. At the final treatment visit
of the study, the overall treatment evaluation (OTE)32
evaluated the magnitude of change in health status on a
15-point scale ()7 to )1 ¼ worse; 0 ¼ no change and
1 to 7 ¼ better) and the Satisfaction Survey (SS)
evaluated patient satisfaction with treatment using a
14-point scale ranging from completely satisfied (7) to
completely dissatisfied ()7).
