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
Neuronal ferroptosis is considered as a key mechanism contributing to neurological deficits during the secondary injury phase following spinal cord injury (SCI). Clusterin (CLU), a stress-responsive protein, has been reported to exert neuroprotective effects and promote neuronal survival in central nervous system injuries. However, its specific role in neuronal ferroptosis remains unclear. Here, we demonstrate that both exogenous recombinant CLU protein and endogenous CLU overexpression significantly inhibit neuronal ferroptosis, as evidenced by reduced lipid peroxidation, decreased iron accumulation, preserved mitochondrial integrity, and modulation of ferroptosis-related genes (upregulation of GPX4/xCT and downregulation of ACSL4). Mechanistically, CLU activates the PI3K-AKT-mTOR pathway, subsequently regulating the SREBP1-SCD1 lipid metabolism axis to suppress ACSL4-mediated lipid peroxidation. Furthermore, AAV-mediated CLU overexpression effectively mitigates pathological damage and significantly enhances motor function recovery in SCI mice. In conclusion, this study reveals a novel mechanism whereby CLU promotes SCI repair by inhibiting neuronal ferroptosis via the PI3K-AKT-mTOR-SREBP1 axis, indicating its therapeutic potential for ferroptosis-targeted neuroprotective strategies.
