Toilet footstool,
does it really help with Less straining, shorter defecation time, and greater sense of complete evacuation?
research showsThe grade is C with 50 points. In a self-controlled study, 52 healthy volunteers used their usual posture for two weeks and a footstool for the next two weeks, recording 1,119 bowel movements. With the device, emptiness improved (ordinal OR 3.64, 95% CI 2.78-4.77), straining fell (OR 0.23, 0.18-0.30), and mean duration fell from 5.60 to 4.24 minutes; no-device/device fold ratio 1.25 (1.17-1.33).

Useful facts when choosing a product
- The device raises the feet so the knees sit above the hips on a Western toilet.
- The article names Squatty Potty but does not report the exact height or model.
- The order was fixed at two weeks without then two weeks with the device; random subject intercepts handled repeated measurements.

What the research actually shows
Fifty-two Ohio State internal-medicine residents and partners recorded 735 bowel movements without the device and 384 with it in a fixed sequence. Random-intercept mixed models handled repeated observations. The 90%, 85%, and 71% figures counted favorable participant-level trend directions, not a 50% response threshold. Poststudy perceived improvement was lower: 65.4% for straining and 50.0% each for emptiness and duration. Mean duration was 5.60 versus 4.24 minutes with a 1.25 (1.17-1.33) no-device/device ratio, but no SD or SE was reported, preventing a standardized mean difference. The exact stool height and model were not stated. Authors declared nothing to disclose; Squatty Potty LLC supplied devices, but company funding or design involvement was not reported.
Why this is classified as C (50)
All three outcomes improved substantially, but one 52-person study with a fixed sequence has two avoidable limitations, giving C with 50 points.
Counterpoint. Four-week results in young healthy volunteers do not establish durable treatment effects in chronic functional constipation.
Rejudgment record. Cross-check applied — All three patient-centered outcomes improved substantially, but evidence came from one fixed-order 52-person self-controlled study
| 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 | E+ | Meets the clinically important threshold |
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 |
|---|---|---|
| Reduced straining | C | Mixed ordinal OR was 0.23 (0.18-0.30). |
| Shorter defecation duration | C | Means were 5.60 versus 4.24 minutes, adjusted ratio 1.25 (1.17-1.33); SD and SE were not reported. |
| Greater sense of complete evacuation | C | Mixed ordinal OR was 3.64 (2.78-4.77). |
