Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Irritable Bowel Syndrome-Symptom Severity Scale | day 0, 28, 56, and 84 | To determine the efficacy of investigational products on the participants global assessment of gastrointestinal symptoms, as assessed by change in Irritable Bowel Syndrome-Symptom Severity Scale total score at the end of study from baseline compared to placebo. Each of these 5 items is scored on a visual analogue scale from 0 to 100. Therefore, the total score on the ranges from 0 to 500. Participants are asked to respond to each question on a 100-point visual analogue scale. The higher the scores, the more will be the severity of symptoms. Participants, if required, can be categorized as having mild (75-175), moderate (175-300), Higher the score is the worst outcome and lower the score is the betterment. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Irritable Bowel Syndrome-Quality of Life | day 0, 28, 56, and 84 | Quality of life as assessed by change in Irritable Bowel Syndrome-Quality of Life. It is a 34-item questionnaire with each item rated on a 5-point scale (34-170), with increasing scores indicating the deteriorating quality of life (Appendix-III). However, to facilitate comparisons among various measures on a standardized scale, the summed scores will be transformed to a 0 - 100 scale ranging from 0 (poor quality of life) to 100 (maximum quality of life). |
| Abdominal Pain Severity-Numeric Rating Scale score. | day 0, 28, 56, and 84 | Abdominal pain severity as assessed by change in Abdominal Pain Severity-Numeric Rating Scale (APS-NRS) score. score ratings include 0 - None, 1 to 3 - Mild, 4 to 6 - Moderate, 7 to 9 - Severe, and 10 = very severe.4 |
| State-Trait Anxiety Inventory-Adults score. | day 0, 28, 56, and 84 | Mental health as assessed by change in State-Trait Anxiety Inventory-Adults (STAI-AD) score. The State-Trait Anxiety Inventory has 40 items, 20 allocated to each S-Anxiety and T-Anxiety sub-scales . The range of scores for each subtest is 20-80, the higher score indicating greater anxiety. A cut point of 39-40 has been suggested to detect clinically significant symptoms for the S-Anxiety scale |
| Bristol Stool Form Scale | day 0, 28, 56, and 84 | At the end of days 28, 56, and 84, the percentage of participants transitioning to normal stool consistency (as demonstrated by weekly BSFS score reported as 3, 4, or 5) compared to baseline scores will be identified to evaluate the efficacy of IP in comparison to placebo. |
| Gut microbiome as assessed by 16S rRNA sequencing of faecal samples. | day 0 and 84 | — |
| Vitals - Pulse Rate | day 0, 28, 56, and 84 | Normal Pulse rate 60 - 100 bpm |
| Vitals - blood pressure | day 0, 28, 56, and 84 | To evaluate the safety of IP consumption . Normal BP ranging Systolic120 - 129 mmHg and or diastolic 80 - 84 mm Hg |
