THERMOGRAPHY ACCURACY IN THE DIAGNOSIS OF CARPAL TUNNEL SYNDROME.
Article in Acta ortopedica brasileira, 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
Objective: To evaluate the accuracy of thermography for diagnosing carpal tunnel syndrome (CTS) compared to electroneuromyography (ENMG), considered the gold standard, in patients with an indication for surgical treatment recruited from the neurosurgery outpatient clinic of the Irmandade da Santa Casa de Londrina. Methods: This is a cross-sectional, descriptive diagnostic accuracy study, oriented by the Guideline for Reporting Reliability and Agreement Studies (GRAAS), with a sample from the database of the project "Clinical-functional characterization and evaluation of the treatment efficacy of patients with carpal tunnel syndrome" of 44 patients, both genders, divided into a study group with 17 participants and a control group with 27 participants. A FLIR® T540 camera was used to capture the thermographic images. The data was acquired and analyzed using FLIR Tools+ software, which measured the average temperature of the region of interest. Artificial Neural Networks were used to classify the thermographic images. Results: In terms of the area under the curve was 0.908, the precision obtained was 90.81%, the accuracy 91.66%, the sensitivity 87.25% and the specificity 94.44%. The F1-score was 88.99%. Conclusion: The main findings, such as the sensitivity and specificity values, showed significant results indicating that thermography is effective in detecting CTS.
