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

purposeThis prospective observational study aimed to examine the effects of the volume of perivascular adipose tissue (PVAT) and the fat attenuation index (FAI) on maturation and primary patency following the formation of an initial arteriovenous fistula (AVF).

methodsThis study enrolled 106 patients who underwent first-time upper limb AVF creation. PVAT volume and FAI were quantified using non-contrast computed tomography (CT) within 2 weeks postoperatively. Patients were monitored for 12 months to evaluate primary patency and maturation. Statistical analyses included receiver operating characteristic (ROC) curve analysis to determine optimal cutoff values for group stratification, Kaplan-Meier survival analysis with the Log-rank tests, and multivariable Cox proportional hazards regression to identify independent risk factors.

resultsA total of 33 patients (31.1%) exhibited adverse events within 1 year. ROC analysis determined the optimal cutoffs for group stratification of 4.32 cm

conclusionsIn this prospective cohort, lower PVAT volume and higher FAI were independently associated with an increased risk of adverse events and decreased primary patency following AVF formation. According to these findings, AVF outcomes may be influenced by the perivascular adipose microenvironment, and PVAT volume and FAI may be useful imaging biomarkers for risk assessment.
