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 aim of this study was to evaluate the clinical and radiological outcomes of posterior malleolar fractures (PMFs) treated surgically via a posterolateral approach and to investigate the prognostic value of Bartoníček-Rammelt fracture morphology in predicting functional outcome, reduction quality, and osteoarthritis development.
methodsIn this single-center retrospective study, 61 patients with PMFs who were treated surgically via a posterolateral approach between January 2020 and December 2023 and had a minimum follow-up of 24 months were included. Fractures were classified ac-cording to the Bartoníček-Rammelt classification (BRC). Clinical outcomes were assessed using the Olerud-Molander Ankle Score (OMAS), while radiological outcomes were evaluated based on articular step-off and the Kellgren-Lawrence osteoarthritis grade. Multivariable linear regression analysis was performed to identify independent predictors of functional outcome.
resultsThe mean follow-up duration was 38.2±8.8 months. The mean OMAS was 89.9±10.2. Articular step-off was <1 mm in 82.0% of the patients. OMAS scores differed significantly among the BRC fracture types (p=0.039), with lower scores observed in more complex fracture patterns. In the adjusted multivariable regression model including fracture morphology, articular step-off, osteoar-thritis grade, syndesmotic fixation, and post-operative complications, articular step-off (p<0.001) and osteoarthritis grade (p<0.001) remained independent predictors of OMAS, whereas fracture morphology was not independently associated with functional outcome.
conclusionBartoníček-Rammelt fracture morphology was associated with functional outcome in unadjusted analyses. How-ever, after adjustment for articular reduction quality, osteoarthritis grade, syndesmotic fixation, and post-operative complications, fracture morphology was not independently associated with OMAS. Articular reduction quality and osteoarthritis grade were the strongest independent determinants of functional outcome, emphasizing the importance of achieving anatomical reduction in PMFs.
