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.
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 transradial (TR) approach is an alternative to the traditional transfemoral (TF) approach for extracranial carotid artery stenting (eCAS). A successful eCAS may be contingent on the geometry of the great vessels. We aimed to analyze the vessel geometry to identify predictors for successful stent placement, enabling tailored approaches.Materials and methodsMulticenter retrospective data was collected from the electronic health record of patients who underwent eCAS from January 2018 to December 2022. Geometric parameters for great vessels were measured using computed tomography angiography (CTA) or magnetic resonance angiography (MRA). A successful approach was defined as completing eCAS without conversion. We performed a geometric analysis of features correlated with complications and successful completion of eCAS.Results1346 patients underwent TF (1081) and TR (265) eCAS. Conversion from TR to TF occurred in 44 cases (17%). Three TF cases required conversion. Complication rates did not differ between approaches (
