Predictors of difficult vascular access during transradial neurointervention: a retrospective study.
Article in Revista da Associacao Medica Brasileira (1992), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThe aim of this study was to identify factors associated with difficulty in establishing vascular access during the transradial approach for neurointerventional therapy.
methodsWe retrospectively analyzed consecutive patients who successfully underwent transradial approach neurointerventional therapy at Fudan Zhongshan Xiamen Hospital (July 2021-July 2024). Patients were categorized as "difficult" or "easy" according to whether vascular access establishment required >15 min. Collected variables included difficulty in radial artery puncture/sheath insertion, feasibility of routinely forming a Simmons-2 catheter, aortic arch type (II-III), tortuosity of the brachiocephalic trunk, brachiocephalic trunk-target common carotid artery angle (<30°), and tortuosity of the C2-C4 internal carotid artery. Multivariate logistic regression was performed to identify independent factors.
resultsAmong 277 patients, 199 were in the easy group and 78 were in the difficult group. Compared with the easy group, the difficult group more frequently had difficult radial puncture/sheath insertion, brachiocephalic trunk tortuosity, a sharp brachiocephalic trunk-target common carotid artery angle (<30°), C2-C4 internal carotid artery tortuosity, and failure to routinely form a Simmons-2 catheter (all p<0.05). Hypertension, diabetes, hyperlipidemia, and type III aortic arch were not significantly different between groups (all p>0.05). On multivariate analysis, difficult radial puncture/sheath insertion, inability to routinely form a Simmons-2 catheter, brachiocephalic trunk tortuosity, a brachiocephalic trunk-target common carotid artery angle <30°, and C2-C4 internal carotid artery tortuosity were independent factors associated with access difficulty (all p<0.001).
conclusionBoth access-site difficulty and unfavorable supra-aortic/internal carotid artery anatomy were independently associated with prolonged vascular access establishment during transradial approach neurointerventional therapy.
