Colchicine Alleviates Non-Atherosclerotic Vascular Aging by Targeting Endothelial Dysfunction and Inflammatory Status.
Article in Journal of inflammation research, 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
Background: Non-atherosclerotic vascular aging (NAVA) contributes to cardiovascular risk through progressive arterial stiffening and endothelial dysfunction. Colchicine, best known for anti-inflammatory activity, has been proposed to protect vascular structure and function. We evaluated whether chronic colchicine mitigates NAVA in a smooth-muscle-specific ERCC1 knockout (SMC-KO) mouse model of DNA-damage-driven vascular aging. Methods: We performed experiments in the SMC-KO treated with colchicine (0.1mg/kg/day) or vehicle from the age of 10 to 22 weeks. Endothelial function was assessed by acetylcholine-induced vasorelaxation, and vascular structure by pulse-wave velocity (PWV), carotid intima-media thickness (cIMT), and elastin integrity. Results: SMC-KO mice developed increased arterial stiffness and impaired acetylcholine-mediated relaxation. Chronic colchicine significantly (p<0.01) lowered PWV, preserved elastin architecture, and improved endothelium-dependent relaxation, while sodium-nitroprusside responses and systemic cytokine levels remained unchanged. Conclusion: Chronic colchicine treatment preserves endothelial function and vascular elastin structure and reduces arterial stiffness in a DNA-damage-driven model of non-atherosclerotic vascular aging. These findings highlight colchicine's pleiotropic vascular benefits beyond anti-inflammation, supporting its potential repurposing for primary prevention in vascular aging and cardiovascular health or the development of colchicine-mimicking drugs with greater selectivity and improved safety profiles.
