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/
objectivesIschemia-reperfusion injury (IRI) contributes to graft dysfunction in solid organ transplantation, with the pancreas vulnerable due to its fragile vasculature. Endothelial glycocalyx (eGCX) disruption is central to this process. This study prospectively examined perioperative endothelial injury in pancreas transplantation.
methodsFifty-two recipients were included, of whom 47 underwent simultaneous pancreas-kidney (SPK) transplantation and 5 pancreas retransplantation. Biomarkers of eGCX degradation (syndecan-1, heparan sulfate (HS) and hyaluronan) and endothelial injury (soluble thrombomodulin, VEGF and soluble VEGFR1) were measured in plasma preoperatively, 10 min after pancreas reperfusion, 24 h later, and at discharge. Associations with donor type and early post-transplant outcomes were explored.
resultsA marker endothelial injury was evident within 10 min of pancreas reperfusion, before kidney implantation, characterized by increased syndecan-1, HS, and sVEGFR1, together with decreased VEGF. Hyaluronan peaked at 24 h, consistent with a broader systemic endothelial response. Controlled donation after circulatory death donors showed higher syndecan-1 levels at 10 min PR and higher VEGF at 24 h. Seven recipients developed pancreas graft loss, which was linked to lower VEGF at 10 min post-reperfusion and lower hyaluronan levels both before surgery and at discharge. Kidney acute tubular necrosis was related with higher preoperative HS and elevated 24 h sVEGFR1. Among recipients with functioning grafts, preoperative endothelial biomarkers were linked to postoperative complications.
conclusionsPancreas transplantation triggers early endothelial injury and glycocalyx shedding, particularly in a predominant SPK setting. Perioperative endothelial biomarkers may have a value for early risk stratification after transplantation.
