Development of a Porcine Model of Arteriovenous Fistula Venous Stenosis Treated with Percutaneous Transluminal Angioplasty.
Article in Journal of vascular and interventional radiology : JVIR, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
purposeTo develop a porcine model for arteriovenous fistula (AVF) venous stenosis (VS) treated with percutaneous transluminal angioplasty (PTA), and to compare outcomes of plain ordinary balloon angioplasty (POBA) to paclitaxel drug-coated balloon (DCB) angioplasty. MATERIALS AND
methodsTwelve castrated male Yorkshire pigs (4-5 months, 35-45 kg) underwent renal artery embolization to induce chronic kidney disease (CKD). Twenty-eight days later, AVF was created by anastomosing the left external jugular vein to left common carotid artery. The pigs were divided into a pilot group (n = 6) for optimizing the AVF technique (euthanized at Day 4) and a definitive group (n = 6) for validating PTA outcomes (euthanized at Day 42). Stenosis developed at juxta-anastomosis 28 days later and was treated with POBA (pilot group, n = 6; definitive group, n = 3) or DCB (definitive group only, n = 3). The definitive group underwent biweekly 4-dimensional flow magnetic resonance (MR) imaging.
resultsAll animals developed CKD, with significant increases in the levels of blood urea nitrogen (increase of median from 2.6 to 3.2 mmol/L; P < .001) and creatinine (increase of median from 10 to 187 μmol/L, P < .001). In the pilot group, 1 animal had an infected fistula, and AVF patency was 1/5. In the definitive group, the patency was 5/6 because the AVF technique was modified by resecting the sternomastoid muscle and increasing the spatulation. At Day 42 after PTA, the DCB-treated AVF outflow vein showed increasing but statistically insignificant blood flow compared with POBA (DCB, 209.8 mm
conclusionsA porcine model of AVF VS treated with PTA was developed, with blood flow trends favoring DCB over POBA.
