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
backgroundIn post-traumatic cubitus varus osteotomy, conventional internal fixation methods typically involve the use of Kirschner wires (K-wires). Nevertheless, with advancements in medical technology and a growing demand for robust internal fixation, surgeons are increasingly opting for cannulated screws. Despite this trend, controversy remains regarding whether cannulated screws are superior to K-wires, particularly in pediatric patients with open epiphyses. This study aimed to compare the clinical treatment outcomes and complications of K-wires and cannulated screws as internal fixation methods in post-traumatic cubitus varus osteotomy procedure in pediatric patients with open epiphyses.
methodsWe conducted a retrospective review of surgical treatments administered to pediatric patients with post-traumatic cubitus varus at our institution between 2010 and 2022. A total of 89 pediatric patients meeting the inclusion criteria were categorized into the K-wire (group A, 54 patients) and cannulated screw (group B, 35 patients) groups based on the internal fixation method used during osteotomy. Comparative analyses were performed on demographic characteristics, imaging results, postoperative complications, hospitalization duration, and plaster and internal fixation duration between the groups. Treatment outcomes were assessed using the Mayo Elbow Performance Score (MEPS) and Flynn criteria.
resultsCompared to pediatric patients in group B, those in group A exhibited shorter durations of plaster (Group A: 46.19 ± 18.44 d, Group B: 49.4 ± 15.74 d) and internal fixation (Group A: 65.48 ± 39.62 d, Group B: 128.14 ± 84.22 d) but an extended hospital stay (Group A: 6.07 ± 1.24 d, Group B: 6.09 ± 1.07 d). On the final follow-up radiographs, significantly smaller humerus-Cobb angles (Group A: 8.64 ± 5.2°, Group B: 8.94 ± 6.65°) and lateral prominence indices (LP) (Group A: 0.34 ± 0.27, Group B: 0.3 ± 0.23) were observed for patients in group A than for those in group B. No significant differences were observed between the two groups in terms of postoperative fixation angle loss (P < 0.05). Additionally, the MEPS scores did not show any statistically significant differences (Group A: 97.78 ± 5.96 points, Group B: 97 ± 6.77 points). During the 6-month follow-up period, no statistically significant differences were observed between the two groups in terms of complications such as scar proliferation, restricted movement, residual deformity, pain, recurrent fractures, and lateral prominence of the epicondyle (P < 0.05).
conclusionFor young children with significant growth potential, K-wires demonstrated superior advantages over cannulated screws. Moreover, compared with cannulated screws, K-wires reduce postoperative discomfort and the risk of complications, providing a more reliable safety assurance for selecting K-wires in young children.
