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
backgroundThe purpose of this study was to investigate the characteristics, treatment methods, and functional outcomes of children with Dubberley Type IIA capitellar fractures.
methodsWe conducted a retrospective analysis of pediatric patients diagnosed and surgically treated for capitellar fractures at the Pediatric Orthopedics Department of Sichuan Provincial Orthopedic Hospital from June 2018 to June 2024. Fractures were classified according to the Dubberley system, and functional outcomes were evaluated using the Mayo Elbow Performance Score (MEPS) at the final follow-up.
resultsAmong the cohort, 26 children (22 males, 4 females; age range 9-14 years, mean 13 years) were identified with Dubberley Type IIA capitellar fractures. All patients underwent surgical treatment via a lateral elbow approach: 11 cases received cannulated screw fixation alone, while 15 cases were treated with cannulated screws combined with buttress plates. Follow-up ranged from 8 to 35 months (mean 17.5 months). At the final follow-up, all fractures had healed without complications such as nonunion, osteonecrosis of the capitellum, or heterotopic ossification. The MEPS excellent/good rate was 100%.
conclusionsThe displacement pattern of Dubberley Type IIA capitellar fractures in children predominantly involves proximal rotation of the lateral aspect of the fracture fragment in the coronal plane, centered on the medial aspect of the fracture fragment. Early and accurate diagnosis combined with surgical intervention resulted in favorable functional recovery and significant therapeutic efficacy. Key factors for successful outcomes include anatomical reduction of the fracture, restoration of joint congruency, stable fixation, and early postoperative functional rehabilitation.
