1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectivesBilateral repetitive transcranial magnetic stimulation (brTMS) has shown promise as a therapeutic approach for depression; however, evidence from existing studies remains inconsistent. To address the concern, a meta-analysis was conducted to examine the efficacy and safety of brTMS in comparison with unilateral repetitive transcranial magnetic stimulation (urTMS) or sham repetitive transcranial magnetic stimulation (srTMS) in treating major depressive disorder (MDD) and bipolar depression (BD).

methodsA systematic search covering publications up to May 22, 2024, was performed across four main bibliographic databases (PubMed, EMBASE, Cochrane Library, and PsycINFO) to identify randomized controlled trials (RCTs) assessing the efficacy and safety of brTMS vs. urTMS or srTMS in patients with MDD or BD. Following Cochrane Handbook guidelines, random-effects meta-analyses were employed to derive pooled estimates for primary and secondary outcomes.

resultsThe analysis included 20 RCTs (8 comparing brTMS to urTMS, 6 comparing brTMS to srTMS, and 6 comparing brTMS to both urTMS and srTMS), encompassing a total of 1666 participants. No significant difference was observed between brTMS and urTMS regarding study-defined response (9 RCTs, 11 study arms, n = 778; RR 1.20, 95% CI 0.83-1.72; Chi

conclusionsThe meta-analysis indicates that brTMS is an effective, safe, and well-tolerated treatment for MDD and BD but does not provide significant antidepressant advantages over urTMS. Consequently, it actually suggested that brTMS could serve as an alternative treatment strategy in cases where urTMS treatment is unsuccessful. Further large-scale studies are needed to explore its efficacy across diverse patient populations, stimulation parameters and to define its role in clinical practice.
