Useful facts when choosing a product
- The comparator was a sham procedure matching treatment duration and other features except intense heat.
- No validated minimal clinically important difference for the 17-item HDRS was provided.
What the research actually shows
Thirty-four adults were randomized, 30 treated, and 29 included in modified intention-to-treat analysis. The comparator was sham treatment. Funding came from nonprofit foundations and private donations. The disclosure listed Raison's Merck speakers' bureau role; no device-manufacturer equity was reported, while patent interests could not be verified.
Why this is classified as C (54)
No device-manufacturer equity was reported, patent interests could not be verified, and the very small sham-controlled trial gives C with 54 points.
Counterpoint. Important limitations and alternative evidence are reported in the Korean text.
Rejudgment record. Cross-check applied — Merck speakers' bureau disclosure, no device-manufacturer equity, unverified patent interests, sham comparator, and small sample
| Endpoint | P | Patient-reported treatment goal - the symptom is the goal |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
The scoring table and the verdict agree (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 |
|---|---|---|
| Primary claim | C | The grade is C with 52 points; this was a 34-person sham-controlled trial. |
