Reliability of Fracture Classifications in Surgically Treated Simple Ankle Fractures.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background Reliable fracture classification is essential for communication, treatment planning, and research. Several systems classify ankle fractures, but their reproducibility remains debated. We evaluated inter- and intrarater reliability and agreement of the Weber, Lauge-Hansen, and AO/OTA classifications among orthopedic and radiology clinicians. Methods We retrospectively identified 265 surgically treated ankle fractures at Randers Regional Hospital, Denmark, from February 2020 to December 2024. Four observers (orthopedic resident, orthopedic consultant, radiology intern, radiology resident) independently classified preoperative radiographs. After three months, they reassessed 50 randomly selected cases. Reliability was quantified using Gwet's agreement coefficient (AC) with 95% confidence intervals and percent agreement. Results The Weber classification demonstrated very good interrater reliability (AC 0.90; 91% agreement). Lauge-Hansen (AC 0.70; 72%) and AO/OTA (AC 0.66; 69%) showed good agreement. Intrarater reliability was highest for Weber across all observers (AC 0.82-0.89). Conclusion The Weber classification provides superior reliability compared with Lauge-Hansen and AO/OTA when applied to plain radiographs of surgically treated ankle fractures.
