Transdiagnostic MRI-derived Features of Psychopathology Following Traumatic Brain Injury: A Systematic Review.
Review in Neuropsychology review, 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
The biological basis of psychopathology outcomes in moderate-severe traumatic brain injury (TBI) remains poorly understood. Previous reviews have found limited convergence in associations between brain regions or functions and specific psychopathology categories (e.g., anxiety, depression). The current systematic review aimed to evaluate MRI-derived features of psychopathology transdiagnostically across available diagnostic categories in moderate-severe TBI. Eligible studies investigated associations between MRI-derived features (macro-, micro-structure, function) and psychopathology in adults with closed-moderate-severe TBI. We searched English literature from Embase, PsycINFO, and MEDLINE via Ovid SP, and the review was last assessed as up to date on 2nd November 2023. Risk of bias was assessed using a customised tool based on the Joanna Brigg's Institute Critical Appraisal Tools. The total number of records screened was 7,777 articles, with 18 meeting eligibility criteria. Studies predominantly investigated hippocampal morphology (n = 7) and depression (n = 9). The average risk of bias fell within the "intermediate" range, associated with sampling, measurement, and statistical bias. Findings were heterogeneous and inconsistent within specific psychopathology categories, yet some morphological features converged transdiagnostically (e.g., hippocampus, thalamus, fronto-temporal regions). Notably, lower hippocampal volume was associated with higher depression (n = 2), anxiety (n = 1), apathy (n = 1), and psychosis (n = 1). No consistent microstructural and functional features converged across studies. This review provides a comprehensive evaluation of the current evidence regarding transdiagnostic MRI-derived features of psychopathology and critiques common limitations across the literature, including the focus on structural MRI, lack of appropriate comparators, and the narrow focus on specific psychopathology categories. We propose that transdiagnostic-dimensional frameworks may help address these gaps and advance the understanding of shared and distinct biological features of psychopathology in moderate-severe TBI.Review Registration: prospectively registered on 6/9/2022 in PROSPERO (CRD42022358358).
