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
backgroundLow transcondylar fractures (LTFs) of the distal humerus are relatively uncommon elbow injuries in elderly patients after low-energy injuries. Although there is still debate regarding the method of fixation, several surgeons prefer bi-columnar fixation using pre-contoured locking plates. However, posterior approaches, which are usually used to perform the above procedure, have disadvantages, such as ulnar nerve neuropathy, damage to the extensor mechanism, and the need for general anesthesia. To solve these problems, the authors designed a combined medial and lateral approach. The purpose of this study was to present the outcomes of bi-columnar internal fixation through a combined medial and lateral approach for the treatment of LTFs of the distal humerus in the elderly.
methodsA total of 46 patients diagnosed with distal humeral fractures between May 2017 and April 2020 were included. Thirty patients were excluded, and 16 patients who underwent open reduction and internal fixation by the medial and lateral approach were selected. We carried out all the surgeries under brachial plexus anesthesia. The clinical outcomes were assessed based on the visual analog scale (VAS) score, Mayo elbow performance score (MEPS), disabilities of the arm, shoulder, and hand (DASH) score, and range of motion (ROM) of the elbow joint. Standardized radiographs were obtained at 3, 6, and 12 months after surgery and at the last follow-up visit to evaluate for bony union and to check for complications, such as ulnar nerve neuropathy and heterotopic ossification.
resultsThe mean age was 81 years (range, 65-91 years). Bony union was achieved in 15 out of 16 patients. The mean VAS score was 2.1 (range, 0-6), the mean MEPS was 84.4 (range, 70-100), and the mean DASH score was 20.6 (range, 9.5-33.6). There were three complications including reduction loss, skin necrosis, and stiffness of the elbow. There was no ulnar nerve neuropathy. The post-operative ROM was 100 degrees or higher in all cases, which did not cause any impairment in daily life.
conclusionLTFs of the distal humerus in the elderly can yield satisfactory results with bi-columnar internal fixation through a combined medial and lateral approach.
