What researchers measure

Primary outcomes

  1. Difference in dyspepsia symptom scores week 8 versus week 0

    The Dyspepsia Symptom Score is calculated from the dyspepsia symptom severity questionnaire at weeks 0, 4 and 8. The symptom score has been used in previous studies (Tack et al., Gastroenterology 1998).

    Time frame: Week 8 compared to week 0

Secondary outcomes

  1. Individual symptom severities

    Individual symptom scores from the dyspepsia symptom score (DSS) which is used as primary endpoint

    Time frame: Week 8 compared to week 0

  2. Nepean dyspepsia index for quality of life in functional dyspepsia

    Use of the validated NDI.

    Time frame: Week 8 compared to week 0
