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

backgroundRadial artery occlusion (RAO) is the most common complication of transradial access. Existing revascularization protocols are not yet standardized, and different revascularization techniques may be employed across centers.

aimsAn innovative protocol named RETRY, which targets the recanalization of the proximal radial artery via distal radial access using specific wire techniques and drug-coated balloons, could be feasible and safe.

methodsWe prospectively collected and analyzed data from 12 consecutive patients undergoing attempted recanalization of RAO via distal radial access between January 2024 and July 2025. Demographic, clinical, and procedural variables were recorded. The primary endpoint was technical success, defined as successful recanalization with restoration of antegrade radial flow on angiography. Secondary outcomes included complications and radial patency at follow-up.

resultsMean patient age was 61.5 ± 12.1 years; mean body mass index was 29.1 ± 3.3 kg/m

conclusionsThe RETRY protocol for RAO recanalization, based on ultrasound-guided distal radial access and drug-coated balloon angioplasty, is feasible, safe, and associated with excellent technical success and favorable short-term patency. As a prospective feasibility study, these findings warrant validation in larger, comparative trials with longer follow-up.
