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

background and purposeThe guided angiography system, an integrated angiography system, enables continuous guidance and flushing during diagnostic procedures. A guidewire provides guidance by remaining inside the catheter during contrast injection into tortuous vessels. While its feasibility was demonstrated in a retrospective study, this randomized controlled trial aims to evaluate its safety and effectiveness. MATERIALS AND

methodsThis single-center, single-blind, randomized controlled trial was conducted from September 2021 to June 2022. Patients with unruptured intracranial aneurysms were enrolled and randomly assigned to either the guided or the conventional group. Primary outcomes were procedural time and serious adverse events. Secondary outcomes included catheterization success, adverse events, fluoroscopy time, fluoroscopy dose, and image quality.

resultsA total of 200 participants (mean age, 59 [SD, 10 years], 71% women) were randomized into the guided (

conclusionsThe guided angiography system offers a simple and effective alternative for diagnostic cerebral conventional angiography, with reduced radiation exposure and a favorable safety profile.
