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
backgroundRadial artery spasm remains a frequent complication during transradial coronary and peripheral angiography. Despite its impact on procedural success and patient discomfort, consistent predictors remain elusive, as does a standard definition.
objectivesThis study aimed to identify independent clinical, hemodynamic, and anatomical predictors of radial artery spasm using data from a single-operator, real-world cohort of patients undergoing both elective and emergency procedures, utilizing an angiographic definition of radial artery spasm.
methodsA retrospective observational analysis was conducted on 96 patients with successful radial artery access. Radial artery spasm was objectively defined as >50% luminal narrowing on radial angiography. Patient demographics, procedural characteristics, comorbidities, and arterial parameters were analyzed. Univariate and multivariate logistic regression models were used to identify significant predictors.
resultsRadial artery spasm occurred in 62.5% of patients. Univariate analysis identified lower height, weight, smaller radial artery diameter, higher pain scores, and lower diastolic blood pressure as associated with radial artery spasm. In multivariate analysis, only lower body weight (β = -0.043,
conclusionsOur findings suggest that low body weight and small radial artery diameter are significant independent predictors of angiographic radial artery spasm, highlighting the importance of anatomical considerations over demographic or clinical factors. Preprocedural assessment of radial artery size may enhance risk stratification and guide preventive strategies. Further multicenter validation is warranted. Incorporating routine evaluation of radial artery size and body habitus into pre-procedural assessment may help identify patients who could benefit from tailored preventive approaches-such as smaller sheath sizes, increased vasodilator use, or ultrasound-guided puncture-to optimize procedural success and patient comfort.
