Correlation between controlled-pressure provocative test duration and electrodiagnostic severity in carpal tunnel syndrome.
Article in Journal of rehabilitation medicine, 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
objectiveTo assess the correlation between controlled-pressure provocative test duration and electrodiagnostic severity in carpal tunnel syndrome.
designCross-sectional correlational study. PATIENTS: Patients with clinical symptoms consistent with carpal tunnel syndrome were recruited from the electrodiagnosis clinic of the Department of Rehabilitation Medicine, Faculty of Medicine Ramathibodi Hospital, Mahidol University, Bangkok, Thailand, between September 2023 and July 2024.
methodsPatients underwent electrodiagnostic studies, and the severity of carpal tunnel syndrome was classified as mild, moderate, or severe according to the 2011 criteria of the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM). Each participant subsequently received a controlled-pressure provocative test. The time to symptom provocation was recorded, with a maximum duration of 30 s. Spearman's rank correlation was used to assess the association between test duration and electrodiagnostic severity.
resultsIn 124 hands, 31, 45, and 48 hands were categorized by the degree of electrodiagnostic severity as mild, moderate and severe, respectively. There was no correlation (ρ = -0.16, p-value = 0.074) between controlled-pressure provocative test duration and electrodiagnostic severity.
conclusionsThere was no correlation between controlled-pressure provocative test duration and electrodiagnostic severity in patient with carpal tunnel syndrome.
