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 Extensor pollicis longus (EPL) tendon rupture is a potential complication following distal radius fracture, typically occurring several weeks after injury. Herein, we present a rare case of acute extensor pollicis longus tendon rupture associated with a distal radius fracture. CASE REPORT A 35-year-old woman visited our hospital with a distal radius fracture. At the time of examination, the thumb could be moved, although there was pain in the wrist. Computed tomography (CT) revealed a fracture line extending to the ulnar side of Lister's tubercle. During volar locking plate fixation, visual confirmation of the EPL tendon injury was conducted. According to the intraoperative finding, the EPL tendon was 70% ruptured and elongated, and the extension mechanism of the thumb was disrupted. Based on these findings, direct suture of the EPL tendon, including elongation of the ruptured tendon, was performed. One year after surgery, the EPL tendon excursion was smooth, with no limitations in thumb mobility, and the patient had returned to work. CONCLUSIONS This case highlights the importance of recognizing that EPL tendon injury can occur in conjunction with distal radius fractures. The risk of the EPL tendon injury is particularly high when the fracture line extends to the ulnar side of Lister's tubercle, which serves as the EPL tendon floor. When an EPL tendon injury is suspected based on preoperative examination and fracture type, it is important to obtain adequate informed consent and to prepare for potential EPL tendon reconstruction before surgery.
