Ultrasound-guided angioplasty of arteriovenous fistula for hemodialysis: initial experience of a single center.
Article in Jornal vascular brasileiro, 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
Chronic Kidney Disease is a growing public health concern and arteriovenous fistulas (AVFs) are the preferred type of vascular access for hemodialysis, but venous stenosis can impair their function. Angioplasty is the first-line treatment, but availability is limited on the public health care system. This retrospective study evaluated the feasibility and early outcomes of ultrasound-guided AVF angioplasty performed at a referral center in 2024. Nine patients were recruited and followed for 3 months. Outcomes included technical success, blood flow, venous diameter, complications, and patency. Technical success was achieved in 77.8% of cases, with increased blood flow and venous diameter. Complications occurred in 66.6%, the majority minor hematomas, although two patients developed acute thrombosis. The technique was feasible and improved hemodynamic parameters, although with a non-negligible complication rate.
