Clinical and Electrophysiological Assessment of Peripheral Nerve Function After Transradial Angiography: A Prospective Study.
Article in Anatolian journal of cardiology, 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
backgroundTransradial angiography (TRA) is widely used in contemporary coronary procedures. Although clinically apparent peripheral nerve injury after TRA is uncommon, subclinical nerve involvement may go unrecognized. This study aimed to objectively assess peripheral nerve function after TRA using neurological examination, standardized neuropathic pain questionnaires, and nerve conduction studies (NCS).
methodsThis prospective, single-center observational study included consecutive patients undergoing transradial coronary angiography. A total of 107 patients were analyzed. Neurological examination was performed within 24-48 hours after the procedure. Neuropathic symptoms were evaluated using the Douleur Neuropathique en 4 (DN4) and Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) questionnaires. Bilateral nerve conduction studies of the median, ulnar, and radial nerves were performed 1 month after TRA, and side-to-side comparisons were conducted.
resultsSide-to-side differences were observed in selected nerve conduction parameters. These electrophysiological changes predominantly involved the radial nerve on the procedure side, characterized by lower sensory amplitude, reduced conduction velocity, and decreased motor amplitude (P < .05). Median and ulnar nerve conduction findings were largely comparable between sides. Douleur Neuropathique en 4 and LANSS scores were in normal ranges and not associated with nerve conduction parameters. No clinically evident local or neurological complications were detected during follow-up.
conclusionTransradial angiography may be associated with mild, procedure-side predominant radial nerve conduction changes detectable by NCS, without clinically evident neuropathy. Objective electrophysiological assessment may therefore help identify underrecognized subclinical nerve involvement following TRA.
