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
Aim: The gold standard nerve conduction study for diagnosing carpal tunnel syndrome is often painful and has variable diagnostic accuracy. This study aimed to evaluate the diagnostic performance of shear wave elastography in correlation with nerve conduction study. Material and methods: A prospective case-control study was conducted on 50 participants (50 wrists), including 25 carpal tunnel syndrome cases diagnosed by nerve conduction study and 25 healthy controls. Shear wave elastography assessed the stiffness of the median nerve at three locations: outside the carpal tunnel, at the inlet, and at the outlet. Cross-sectional area measurements were also obtained using B-mode ultrasound. Receiver operating characteristic curves were used to evaluate diagnostic performance. Results: Shear wave elastography and cross-sectional area demonstrated high diagnostic accuracy for carpal tunnel syndrome, with a cut-off value of ≥63.5 kPa inside the tunnel (mean of inlet and outlet values) and a cross-sectional area cut-off of ≥0.08 cm Conclusions: Shear wave elastography is a reliable, non-invasive modality for carpal tunnel syndrome diagnosis, offering excellent specificity, particularly when combined with cross-sectional area. Additionally, shear wave elastography at the tunnel inlet may help identify severe carpal tunnel syndrome, supporting timely clinical decision-making and prioritization of intervention.
