Diagnostic accuracy of ultrasonography compared with nerve conduction studies in carpal tunnel syndrome.
Article in Frontiers in neurology. 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
Introduction: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy of the upper extremity. Ultrasonography (USG) enables measurement of the median nerve cross-sectional area (CSA) and quantitative assessment of hand muscles. This study aimed to evaluate the diagnostic accuracy of USG findings compared with electrophysiological studies in CTS. Methods: In this prospective cross-sectional study, we included 136 wrists from 76 patients presenting to the Neurology Department of Ondokuz Mayıs University between July 2023 and December 2023. Ultrasonographic findings were compared with electrophysiological results. Results: The cut-off value for median nerve CSA in the diagnosis of CTS was 0.0905 cm Conclusion: Ultrasonography showed excellent diagnostic accuracy in detecting carpal tunnel syndrome, with high agreement with electrophysiological findings. Among the evaluated parameters, median nerve cross-sectional area and thenar muscle thickness were strong diagnostic indicators. These results support the role of ultrasonography as a reliable, non-invasive diagnostic tool in CTS. Further large-scale, multicenter studies are warranted to confirm these findings and to define standardized diagnostic thresholds.
