Theta burst stimulation of extrastriate body area for body perception in anorexia nervosa: a randomized controlled trial.
Trial report in Translational psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Anorexia nervosa is a severe and potentially life-threatening psychiatric disorder characterized by self-starvation, intense fear of weight gain, and a distorted body perception. Treatment remains challenging, and effective interventions for adults are limited. The extrastriate body area (EBA), a cortical region involved in body representation, may contribute to the body perception disturbances. In this double-blind, placebo-controlled, randomized proof-of-concept trial, we investigated the therapeutic potential of targeted theta burst transcranial magnetic stimulation (TMS) of the EBA in patients with anorexia nervosa (n = 40). Participants received four weeks of active (n = 10) or sham (n = 10) TMS combined with body perception training, while a treatment-as-usual group (n = 20) and a healthy control group (n = 40) served as comparators. Improvements in the primary outcome measure, the Body Shape Questionnaire, differed across groups over time, with active TMS showing faster improvement (after 4 weeks) relative to both control groups, that was sustained at 6 months follow-up. Moreover, active stimulation was associated with changes in EBA responses to self- versus non-self touch, shifting neural activity patterns more closely to those of healthy individuals. These findings provide preliminary evidence that individualized neuromodulation targeting a disorder-relevant neural substrate combined with behavioral training shows potential for effectively recalibrating disturbed body perception. By integrating brain stimulation with behavioral training, this study exemplifies a precision psychiatry approach that links neurobiological mechanisms to personalized therapeutic interventions in anorexia nervosa.
