Early treatment-related changes in dorsolateral prefrontal cortex activity and functional connectivity as potential biomarkers for antidepressant response in major depressive disorder.
Article in Translational psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Cognitive deficits are prevalent in major depressive disorder (MDD). Given that the dorsolateral prefrontal cortex (DLPFC) is a crucial region within the executive control network, its activity and functional connectivity (FC) may serve as potential indicators of antidepressant response. This prospective cohort study recruited 115 MDD patients and 43 healthy controls. Psychological assessments, electroencephalogram and event-related potential recordings were performed at baseline and 1 week after venlafaxine treatment, with a 12-week follow-up. Independent sample t-tests and Mann-Whitney U tests analyzed group differences, while linear mixed-effects models and logistic regression evaluated associations between DLPFC activity/FC changes and clinical outcomes. The MDD group showed significantly reduced right DLPFC current density during the N2 time window evoked by oddball stimuli (p = 0.028). Higher right DLPFC current density during the N2 time window was correlated with lower HAMD-21 scores one week after treatment (p = 0.041, n = 46). Furthermore, an early increase predicted remission at week 12 (p = 0.005). Decreased beta-band FC between the left DLPFC and both side of posterior cingulate cortex (PCC) (left: p = 0.003; right: p = 0.004) were correlated with lower HAMD-21 scores (n = 71). Moreover, an early reduction in these connectivity measures (left: odds ratio (OR) = 0.534, 95% confidence interval (CI): 0.297-0.972, p = 0.036; right: OR = 0.533, 95% CI: 0.299-0.950, p = 0.033) predicted remission at week 12. Early changes in DLPFC activity and FC may serve as biomarkers for monitoring treatment efficacy and predicting clinical outcomes, informing personalized treatment approaches.
