Soluble CD146 reflects altered endothelial and metabolic homeostasis in peripheral artery disease.
Article in Angiogenesis, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00377897 (Optimisation d'un Produit de thérapie Cellulaire Autologue Par Cellules mononucléées médullaires Dans l'ischémie Critique Des Membres inférieurs liée à l'athérosclérose), which is not on this map.

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.

Abstract
backgroundPeripheral Arterial Disease (PAD) is a prevalent but underdiagnosed pathology. Soluble CD146 (sCD146) was described as a marker of endothelial dysfunction and vascular congestion.
objectiveWe hypothesize that sCD146 may represent a novel biomarker of PAD. Our objective was to evaluate the association between plasma sCD146 levels and the occurrence and severity of PAD.
methodsIn this case-control study, 184 Caucasian men with symptomatic PAD were compared to 163 age-matched healthy control patients. PAD diagnosis was confirmed using ankle-brachial index (ABI) and imaging. Plasma sCD146 was quantified using ELISA. Associations with clinical and biochemical parameters were analyzed through multivariable logistic regression models.
resultssCD146 level was significantly reduced in PAD patients (mean [95% CI]: 288 ng/mL [269-306]) versus control patients (480 ng/mL [460-500], p < 0.0001). A 10 ng/mL decrease in sCD146 was associated with an age-adjusted odds ratio (OR) of 1.17 (95% CI 1.13-1.22) for PAD, increasing to OR 1.25 (95% CI 1.14-1.36, p < 0.0001) after adjustment for risk factors. sCD146 was not associated with PAD severity (by Fontaine stage). Notably, the association between sCD146 and HDL-C was positively correlated in controls (β = 0.220, p = 0.005), but negatively correlated in PAD patients (β = - 0.156, p = 0.041), with significant interaction (p = 0.002). Age-adjusted OR for PAD was highest in individuals with high HDL-C tertiles (OR = 1.41, 95% CI 1.22-1.63).
conclusionA lower sCD146 concentration is independently associated with PAD. Additionally, an inverse relationship was observed between HDL-C and these patients. These findings suggest that sCD146 may reflect impaired endothelial homeostasis and metabolic dysregulation in PAD, indicating that it could serve as a diagnostic biomarker for the pathology.
