Machine learning-based prediction model for paresthesia improvement after open carpal tunnel release: a preliminary study.
Article in BMC musculoskeletal disorders, 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
backgroundCarpal tunnel syndrome (CTS) is the most common entrapment neuropathy of the hand. While carpal tunnel release surgery generally provides good outcomes, some patients continue to experience persistent paresthesia postoperatively. This study aimed to develop a machine learning-based prediction model for paresthesia improvement following carpal tunnel surgery.
methodsWe retrospectively analyzed 94 hands from 83 patients who underwent carpal tunnel release surgery between April 2021 and March 2024. Paresthesia improvement was evaluated at 1-year follow-up using a 10-point scale, with excellent improvement defined as scores 0-1. Three machine learning algorithms (Support Vector Machine, Random Forest, and Logistic Regression) were compared. Model performance was evaluated using accuracy, precision, recall, F1-score, and area under the ROC curve (AUC).
resultsOf 94 hands, 53 (56.4%) achieved excellent paresthesia improvement. The optimized SVM model demonstrated the best performance with an AUC of 0.852, accuracy of 78.9%, precision of 88.9%, and recall of 72.7%. The five most important predictive factors were: distal motor latency (DML), age, disease duration, thenar muscle atrophy, and thumb opposition deficit.
conclusionsOur preliminary machine learning model successfully predicted excellent paresthesia improvement after carpal tunnel surgery with good accuracy using five easily obtainable clinical parameters. This pilot study provides a foundation for developing more robust prediction tools that could assist in preoperative counseling and treatment planning. CLINICAL
