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
Background: Depression is a common mental disorder and a leading cause of disability, affecting approximately 280 million people worldwide. Its pathological mechanisms are closely linked to neurotransmitter homeostasis imbalance and neuroplasticity impairment. We aimed to systematically evaluate the clinical efficacy of virtual reality (VR) training in improving depression and to elucidate its dual-pathway regulatory mechanism involving neurotransmitter-plasticity interactions. Methods: We systematically searched PubMed, Web of Science, CNKI, and ScienceDirect databases from their formation to May 2025 to identify randomised controlled trials (RCTs) assessing VR-based interventions. Given the significant heterogeneity across protocols, we conducted a narrative synthesis in accordance with the Synthesis Without Meta-analysis (SWiM) reporting guidelines rather than a quantitative meta-analysis. We assessed the quality of the included studies using the Physiotherapy Evidence Database (PEDro) scale. Results: Based on 16 studies, we found that VR training can significantly alleviate depressive symptoms through multimodal sensory stimulation and immersive interactions, as the included RCTs generally reported reductions in depression scale scores. Preliminary evidence from several studies also suggests a positive correlation between clinical efficacy and biomarkers of neural structure recovery and functional network synchronisation. However, due to high heterogeneity in intervention protocols, control group designs, and outcome measures, we were unable to provide a unified estimate of the VR training efficacy. Conclusions: Evidence suggests that VR training may reverse the pathological cycle of depression through a synergistic dual pathway of neurotransmitter regulation and neuroplasticity enhancement, offering a novel strategy for precision intervention. Future research should optimise VR intervention protocols, explore synergistic effects with traditional therapies, and validate its long-term efficacy and safety in special populations.
