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

backgroundDrug-coated balloons (DCBs) improve the patency of hemodialysis access, yet restenosis rates remain substantial. This may be partly attributable to suboptimal balloon sizing. The relationship between the balloon diameter ratio (BDR; the ratio of DCB diameter to final predilation balloon diameter) and restenosis risk has not been clearly elucidated.

methodsThis retrospective study analyzed 123 patients who underwent DCB angioplasty for dysfunctional arteriovenous fistulas (AVF) or arteriovenous grafts (AVG). The primary endpoint was clinically driven target lesion restenosis within six months. Multivariable Cox regression and restricted cubic spline (RCS) analyses were used to evaluate the association between BDR and restenosis.

resultsThe six-month restenosis rate was 25.2%. BDR was an independent predictor of restenosis (

conclusionsBDR is a key, modifiable technical factor influencing patency after hemodialysis access intervention. Maintaining a BDR within the 0.9-1.1 range correlates with the lowest 6-month restenosis risk, yielding a clear and practical technical target for optimizing DCB angioplasty procedures.
