1 · What the graph read from 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.

2 · The registry

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

objectiveTo compare the efficacy and safety of ultrasound-guided sharp recanalization (USR) with those of conventional percutaneous transluminal angioplasty (PTA) in the treatment of venous valve-related stenosis (VVRS) in arteriovenous fistulas (AVFs).

methodsThis single-center retrospective cohort study included patients treated between January 2023 and June 2024. Seventy-eight patients met the inclusion criteria; after excluding 13 patients lost to follow-up, 65 were analyzed (USR n = 33; PTA n = 32). One-to-one propensity score matching generated 32 matched pairs (USR n = 32; PTA n = 32). The primary outcome was 12-month primary patency; secondary outcomes included technical success, time to restenosis, and complications.After propensity score matching, 32 matched pairs were analyzed.

resultsIn the matched cohort, 12-month primary patency was higher with USR than with PTA (62.5% vs. 25.0%; HR = 0.36, 95% CI 0.18–0.70; P = 0.002). Mean time to restenosis was longer in the USR group (8.25 ± 3.42 vs. 4.48 ± 2.87 months; P = 0.021). Complications were not significantly different between groups (USR 11/32 vs. PTA 5/32), and none required open surgical intervention.

conclusionUSR may improve 12-month primary patency in VVRS compared with PTA without an observed increase in complications. Larger multicenter prospective studies are needed to confirm these findings.
