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
Objectives: Proper catheter selection during right trans-radial coronary angiography reduces procedure duration, costs, and vascular complications. The correlation between aorta morphological parameters assessed through computed tomography (CT) and requirement for larger catheter size was investigated in this study. Materials and Methods: This observational study includes 206 patients who underwent right trans-radial coronary angiography and had already undergone coronary CT angiography at a recognized center from April 2023 to January 2025. Patients who completed angiography using a Judkins left (JL) 3.5 (Group 1) catheter were compared with patients who required catheter exchange with a JL 4 or larger (Group 2). Both groups had their CT images analyzed for four specific aortic morphological variables. Results: A total of 167 patients formed Group 1, whereas 39 patients formed Group 2. The significant differences were detected in the maximal area and length of the ascending aorta among the four aortic CT variables. In multivariable logistic regression model, the strongest association with the need for JL4 or more catheter (Group 2) was found with the maximal area of the ascending aorta (odds ratio [OR] 31.82 [(95% confidence interval [CI]) 1.21-831.18], Conclusion: Maximum area (with derived diameter) and ascending aortic length were the good predictors for suitable catheter selection during right trans-radial invasive coronary angiography.
