rTMS,
does it really help with Acute symptomatic remission of treatment-resistant major depressive disorder?
research showsThe grade is B. Publicly funded OPT-TMS randomized 199 participants and analyzed 190 by intention to treat; three-week remission was 14.1% versus 5.1%, adjusted OR 4.2 (95% CI 1.32 to 13.24; P=0.02). Sham-controlled evidence also supported remission, but short acute treatment and follow-up limit the conclusion, giving B with 76 points.
ads claimA roughly fivefold remission relative risk does not mean that half of patients remit. The evidence concerns repeated, standardized treatment delivered in clinical settings.
Useful facts when choosing a product
- OPT-TMS randomized 199 and analyzed 190 by intention to treat; O'Reardon randomized 325 and used a prespecified evaluable analysis of 301.
- The 2014 review included 18 trials overall, but pooled 14 trials/564 participants for mean difference, 14/605 for response, and 7/332 for remission.
- Verdict 1486 is C with 54 points for the shorter iTBS protocol; this verdict concerns standard high-frequency rTMS.
What the research actually shows
OPT-TMS randomized 199 participants and analyzed 190 by intention to treat. It was funded by NIMH and used electrical scalp stimulation for sham; patient and evaluator guesses did not significantly exceed chance, while treaters guessed above chance but with low confidence. O'Reardon randomized 325 and used a prespecified evaluable analysis of 301: the MADRS primary analysis was not significant at P=0.057. P=0.038 came from a post hoc 295-person analysis excluding six participants. George, Avery, McDonald, Lisanby, and others overlapped across the two trials. The Gaynes review included 18 trials overall, but the actual pooled denominators were 14 trials/564 participants for mean difference, 14/605 for response, and 7/332 for remission.
Why this is classified as B (76)
The wider sham-controlled evidence from multiple teams replicated acute remission and response, with clinical importance anchored to binary remission; overlapping investigators and short acute treatment and follow-up limit the grade to B with 76 points.
Counterpoint. This acute verdict does not determine the optimal targeting, intensity, or maintenance schedule.
Rejudgment record. Cross-check applied — Accepted repeated acute remission benefit across the broader sham-controlled evidence while accounting for overlapping investigators and short acute treatment and follow-up
| Endpoint | P | Patient-reported treatment goal - the symptom is the goal |
| Replication | R2 | Independently replicated across trials |
| Independence | I1 | Mixed funding sources |
| Effect size | E+ | Meets the clinically important threshold |
The scoring table and the verdict agree (B).
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 remission at the end of acute treatment | B | The broader sham-trial evidence across multiple teams and the meta-analysis point in the same direction. |
| Long-term maintenance of remission | ? | The confirmed acute trials do not establish durability. |
