Association between flat variants of the peroneus brevis tendon and split tears on magnetic resonance imaging.

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
objectivesTo determine whether the peroneus brevis tendon shape, cross-sectional area, and patient age are associated with split tears on magnetic resonance imaging.
methodsThis retrospective cross-sectional study included 358 patients (179 with and 179 without split tears), with sample size based on an a priori power calculation (Cramér's V = 0.186, 80% power, α = 0.05). Musculoskeletal radiologists assigned patients to split tear or no-tear groups based on MRI findings 8 weeks before independent shape classification and area measurements. Tendon shape was visually assessed on transverse proton density images and categorized as oval, general flat, flattened with medial convexity, or flattened with lateral convexity. Associations with split tear were evaluated using multivariable logistic regression.
resultsFlat-shaped tendons were more common in the split tear group (91.6%) than in controls (82.1%), while oval tendons were less frequent (8.4% vs. 17.9%, p = 0.007). The flattened with lateral convexity shape was most strongly associated with split tear. In the multivariable analysis, flat shape (odds ratio [OR] = 2.26, p = 0.021), larger cross-sectional area (OR per mm
conclusionsA flat-shaped peroneus brevis tendon, an increased cross-sectional area, and older age are associated with an increased likelihood of peroneus brevis split tears. These features may serve as anatomical imaging biomarkers for early risk identification.
