Method: This was a randomised, single-blind, placebo-controlled clinical trial. Participants were randomly allocated into intervention (inulin) and control (placebo) groups for 8 weeks. Assessments included dietary intake, anthropometric measurements, and IBS symptoms.

Outcome Measures

Primary Outcomes (1)

  • Irritable Bowel Syndrome - Symptom Severity Score/(IBS-SSS)

    The IBS-SSS scale was used to assess the severity of irritable bowel syndrome symptoms. This scale consists of a total of 5 questions, each of which is scored between 0 and 100. The questions provide information about the severity and frequency of abdominal pain, the severity of abdominal distension, the level of satisfaction with bowel habits and the impact of the disease on quality of life. An increase in the score obtained from the scale indicates an increase in symptom severity. ROC (Receiver Operating Characteristic) analysis was applied for the cut-off point of the scale. Accordingly, the cut-off point was calculated as 217.5.
