What the research actually shows
Arslan and Eser studied 35 older residents in two Turkish nursing homes. The 14-day single-group repeated-measures design used seven baseline days, a 60-minute abdominal pack on each of three days, and four post-treatment days. Bowel frequency and stool amount did not improve, while consistency, straining, and complete evacuation did. Publicly accessible reporting did not provide a separate controlled result for laxative use, and a between-group calculation is impossible because there was no control group.
Why this is classified as C (46)
Patient-relevant symptom signals exist, but no comparator or between-group magnitude is available, giving C with 46 points.
Counterpoint. The uncontrolled study is not definitive proof of no effect either.
Rejudgment record. Cross-check applied — Some symptom signals in a 35-person uncontrolled before-and-after study, without a comparator or estimable between-group magnitude
| Endpoint | P | Symptom or function itself is the target - including patient reports and performance tests |
| Replication | R1 | Single confirmatory trial |
| Independence | I1 | Mixed funding sources |
| Effect size | EX | The clinical size of the effect could not be judged |
Stored derived and displayed grades match; this is not a current recalculation or validity check (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Increased bowel-movement frequency | D | No significant within-group change was found. |
| Improved consistency, straining, and complete evacuation | C | Symptoms improved over time, but there was no control group. |
