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
Objectives: This study investigates the effectiveness of ankle distraction arthroplasty (ADA) using the Ilizarov frame in treating end-stage ankle osteoarthritis (OA) by evaluating changes in cartilage volume through semi-automatic MRI segmentation. Methods: The study involved 42 end-stage post-traumatic ankle OA patients from 2021 to 2023. Magnetic resonance imaging (MRI) scans were conducted before surgery and 12 months post-treatment. Changes in cartilage volume of the talus and tibia were measured using semi-automatic segmentation methods. statistical significance was assessed using the non-parametric Wilcoxon signed-rank test. Results: Out of 42 patients, 10 completed the study with MRI scans of sufficient quality. Significant increases in cartilage volume were observed: talus cartilage increased by 247.48 mm Conclusion: The findings demonstrate that ADA using the Ilizarov frame is effective in increasing cartilage volume in patients with end-stage ankle OA. Semi-automatic MRI segmentation is a reliable method for monitoring these changes. Further research with larger sample sizes is necessary to validate these findings and assess long-term outcomes.
