Fig. 3. — Distribution of occurrence frequency and distress severity of gastrointestinal symptoms. (A) Abdominal stretching occurrence frequency; (B) abdominal cramping distress severity; (C) diarrhoea occurrence frequency; (D) diarrhoea distress severity; (E) bloating occurrence frequency; (F) acid regurgitation distress severity; (G) flatulence occurrence frequency; (H) flatulence distress severity.
