Large-scale neural network correlates of response inhibition associated with antidepressant response in major depressive disorder.
Article in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundA fundamental impairment of major depressive disorder (MDD) is response inhibition, which may serve as a predictor for inadequate responses to antidepressants. Nevertheless, the neurophysiological connections between treatment outcomes and response inhibition are not yet fully understood.
methodsThis study involved 149 participants, consisting of 77 healthy controls (HCs) and 72 patients with MDD. All individuals undertook a Go/No-go task while undergoing magnetoencephalography (MEG) recording. Those patients with MDD showing at least a 50% decrease in symptom severity (the short 6-item version of Hamilton Depression Rating Scale) after four weeks were classified as responders. We assessed whole-brain connectivity within the beta-band.
resultsIndividuals with MDD demonstrated decreased connectivity in a right-lateralized network centred on inferior frontal gyrus. Additionally, non-responders displayed reduced functional connectivity in a left-dominant frontoparietal network centred on superior parietal gyrus and orbitofrontal cortex during response inhibition when compared to both responders and HCs. This identified dysregulation also has potential predictive value regarding the response to antidepressant treatment.
conclusionsHypoconnectivity in the left-lateralized frontoparietal network centred on superior parietal gyrus and orbitofrontal cortex indicate a decompensatory mechanism that may contribute to an insensitivity toward antidepressant interventions.
