Endovascular Intervention and the Vascular Glycocalyx in Patients with Chronic Limb-Threatening Ischaemia: A Prospective Observational Study.
Observational study in International journal of molecular sciences, 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
This single-center prospective observational study evaluated peri-procedural changes in circulating markers of endothelial glycocalyx injury in patients with chronic limb-threatening ischemia undergoing lower extremity endovascular treatment. Fifty patients (mean age 72.2 years; 56% with diabetes mellitus; 42% current smokers) underwent percutaneous transluminal angioplasty, most commonly involving the femoropopliteal segment and using 4F introducer sheaths. Serum concentrations of syndecan-1, heparan sulfate, and hyaluronic acid were measured using ELISA before and one day after the procedure. No significant differences were observed between baseline and post-procedural biomarker levels, with minimal median changes, overlapping interquartile ranges, and negligible paired effect sizes. Although individual biomarker trajectories demonstrated considerable interindividual variability, no consistent directional trend was identified. Furthermore, demographic and clinical factors, including age, sex, diabetes, and smoking status, as well as procedural variables such as stent implantation, sheath size, and intervention level, were not associated with biomarker changes in univariate or multivariable analyses. These findings suggest that contemporary endovascular revascularization is biologically well tolerated and does not induce detectable systemic endothelial glycocalyx disruption. Nevertheless, the interpretation of these findings is limited by the moderate sample size and single-center design of the study. In addition, syndecan-1, heparan sulfate, and hyaluronic acid are not exclusive markers of endothelial glycocalyx injury and may also reflect extracellular matrix turnover and tissue remodeling.
