Exploring Subtypes Based on Depression and Anxiety in Preoperative Patients With Carpal Tunnel Syndrome: A Two-Step Cluster Analysis.

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
Background Although a growing body of literature supports the importance of depression and anxiety, the assessment of these modifiable factors has not been considered in recent clinical practice guidelines for patients with carpal tunnel syndrome (CTS). This study aimed to classify patients with CTS into preoperative subgroups using cluster analysis based on the Japanese versions of the Self-Rating Depression Scale (SDS) and Pain Anxiety Symptom Scale-20 (PASS-20). Outcome measures were also compared for each cluster. Methods Data from 65 patients with CTS were analyzed. The SDS and PASS-20 psychological parameters were grouped using the K-means cluster method, according to Ward's method. Sociodemographic, disease-related, physical, psychological, and disability outcomes were compared between the clusters. Results A three-cluster solution, which categorized patients into "psychologically normal," "only depression," and "psychologically impaired" clusters, was selected. Upper extremity disability in the "psychologically impaired" cluster was more severe compared to that in other clusters. Conclusions We provided evidence for the detection of depression and anxiety in patients with CTS at a preoperative period.
