Effect of home-based transcranial direct current stimulation combined with nutritional counseling therapy on binge eating disorder symptoms: a randomized pilot trial.
Trial report in Revista brasileira de psiquiatria (Sao Paulo, Brazil : 1999), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
objectiveTo examine the effect of nutritional counseling therapy (NCT) combined with transcranial direct current stimulation (tDCS) on binge eating disorder (BED) symptoms.
methodsForty women with BED were randomly allocated (2:2:2 ratio) to one of the following groups: active tDCS (a-tDCS), NCT, sham tDCS (s-tDCS) with NCT, and a-tDCS with NCT. Home-based tDCS was applied to the dorsolateral prefrontal cortex for 28 sessions.
resultsA mixed analysis of variance (ANOVA) showed no main effect between groups nor a time × group interaction. However, a significant main effect was found for time on the primary outcome Binge Eating Scale (BES) (p = 0.001; eta2p = 0.325), which tended to decrease during treatment and follow-up. A significant main effect was found for the secondary outcome short-interval intracortical inhibition (SICI) (p = 0.02; eta2p = 0.112), a measure of inhibitory function, which increased from baseline to the final period in the a-tDCS group, without significant differences between groups.
conclusionCombined NCT and tDCS did not have a synergistic effect on BED symptoms. Nevertheless, the data from this pilot study should help plan future larger-scale studies investigating the effects of tDCS and behavioral interventions in the promising area of BED treatment.
