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: Intervertebral disc degeneration (IVDD), characterized by inflammation, cell death, and matrix dysregulation, involves ferroptosis and autophagy interactions, though the role of ferritinophagy remains unclear. Methods: This study integrated bioinformatics analysis of clinical transcriptomes, single-cell sequencing, and experimental models to identify molecular targets linking ferritinophagy to IVDD progression. Results: Multi-omics analysis revealed 10 ferroptosis-related hub genes (eg, NCOA4, TP53, SLC7A11) enriched in hypoxia, autophagy, and ferroptosis pathways. Single-cell profiling demonstrated dynamic shifts in nucleus pulposus cell (NPCs) phenotypes during degeneration, with increased pro-inflammatory monocyte/macrophage infiltration. Clinical and experimental validation showed elevated NCOA4 and ACSL4 (ferroptosis drivers) alongside reduced GPX4 and FSP1 (anti-ferroptotic factors) in degenerated discs. Mechanistically, NCOA4-mediated ferritinophagy promoted iron overload and lipid peroxidation by degrading ferritin, exacerbating oxidative damage. Resveratrol, a natural anti-inflammatory compound, mitigated IVDD in rat models by restoring disc height, suppressing IL1β, TNF-α, and IL6, and reversing ferroptosis/autophagy imbalance via NCOA4 downregulation. Cellular studies confirmed that resveratrol attenuated LPS-induced NPCs degeneration by blocking NCOA4-dependent ferritinophagy, reducing lipid peroxidation and cell death. Conclusion: This work identifies NCOA4 as a critical nexus coordinating ferroptosis-autophagy crosstalk in IVDD and establishes ferritinophagy as a novel pathological mechanism. Resveratrol's therapeutic efficacy, mediated through multi-target modulation of inflammatory and iron homeostasis pathways, provides a promising strategy for IVDD treatment. The findings advance precision medicine approaches by elucidating ferritinophagy's role and proposing resveratrol as a targeted intervention to disrupt this self-amplifying cycle of oxidative damage in disc degeneration.
