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

purposeTransradial access for neurointerventional procedures has increased in popularity over the past few years due to data from extrapolated interventional cardiology studies, patient preference, and early reports of feasibility using this approach. Our aim was to evaluate the incidence of periprocedural stroke in patients undergoing transradial versus transfemoral access for diagnostic cerebral angiograms.

methodsWe retrospectively reviewed our neurointerventional database and identified all patients who underwent a diagnostic angiogram between May 2019 and July 2021. Patients were further divided into transradial versus transfemoral access. In patients with postprocedural stroke, symptoms and National Institute of Health Stroke Scale score were recorded. Pertinent laboratory values and procedural data was reviewed, including COVID status, platelet count, International normalized ratio (INR), Glomerular filtration rate (GFR), vessels catheterized, amount of contrast used, and fluoroscopy time. Imaging work-up for stroke symptoms was reviewed, if available.

resultsThousand two-hundred thirty eight diagnostic cerebral angiograms with 656 patients (53%) undergoing transradial access. Stroke symptoms after angiogram were only observed in the transradial group (5 patients; 0.4% total and 0.8% among radial access cases, respectively). Symptoms included word finding difficulty, paresthesia, or weakness. Three patients underwent cross-sectional imaging, computed tomography was negative in all three patients. Magnetic resonance imaging showed small, scattered infarcts in two patients. All symptoms resolved without additional hospitalization.

conclusionIn our experience, using transradial access for diagnostic cerebral angiograms was associated with a low but not negligible incidence of periprocedural strokes. Patient anatomy should be evaluated prior to selection of vascular access. Patients should be made aware of a slightly higher periprocedural stroke risk with transradial access.
