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
Introduction: Complex proximal ulna fractures that are associated with radial head dislocation or fracture-dislocation, often referred to as "Monteggia-like" or trans-ulnar fracture-dislocations, constitute a heterogeneous group that poses challenges for classification and treatment. Management often relies on surgeon expertise rather than systematic approaches, leading to poor outcomes, high complication rates, and frequent surgical revisions. We hypothesize that a systematic, coronoid-centric, step-by-step surgical technique could improve outcomes in trans-ulnar fracture-dislocations. Methods: A retrospective study was conducted on patients with trans-ulnar fracture-dislocations treated between 2017 and 2023. Exclusion criteria included patients younger than 18 years, open fractures beyond Gustilo grade 1, and follow-up shorter than 12 months. Fractures were classified using the coronoid-centric Mayo classification based on preoperative radiographs and CT scans. Two additional fracture patterns, characterized by distinct coronoid detachment features, were identified. Outcomes were evaluated through subjective elbow scores Subjective Elbow Value, Mayo Elbow Performance Score (MEPS), Oxford Elbow Score, QuickDASH, and range of motion (ROM) evaluations. Results: Among the 39 patients included, the most common fracture pattern was the trans-ulnar basal coronoid fracture-dislocation (49%). At a mean follow-up of 3.9 years (range 1-7), 90% (35/39) of the patients achieved a functional ROM. The mean MEPS was 85 (range 60-100), and the mean QuickDASH was 18 (range 0-45). The revision rate was 13% (5/39), due to coronoid nonunion (n = 1), olecranon fixation failure after a new trauma (n = 1), and elbow stiffness (n = 3). Ulnar nerve neuropathy was recorded in 2 of 39 patients. Discussion: A systematic, coronoid-centric surgical approach led to satisfactory outcomes in trans-ulnar fracture-dislocation with an acceptable rate of complication and revision rate. Recognizing the prognostic value of the coronoid may reduce complication rates. Level of Evidence: Level III. See Instructions for Authors for a complete description of levels of evidence.
