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
Introduction: Anterior talofibular ligament injury is the most common type in chronic ankle instability patients. While initial injuries are often treated conservatively, some patients still require surgery. Shear wave elastography provides quantitative, accurate assessment of ligament damage, offering an objective basis for surgical planning and rehabilitation monitoring. Method: Shear wave elastography quantified shear wave velocity of bilateral anterior talofibular ligaments in neutral and stressed positions in 30 chronic ankle instability patients' group and 60 healthy controls' group. Functional assessments included the Cumberland Ankle Instability Tool, American Orthopaedic Foot & Ankle Society scale, Foot and Ankle Ability Measure for Activities of Daily Living and Foot and Ankle Ability Measure for Sports (FAAM-S) and Visual Analogue Scale for pain. Results: Inter-observer and test-retest reliability for anterior talofibular ligament shear wave velocity were excellent (neutral position: intraclass correlation coefficient = 0.87, 0.93; stressed position: intraclass correlation coefficient = 0.89, 0.96). Shear wave velocity showed no significant differences by gender, age or body mass index. Chronic ankle instability patients had significantly higher shear wave velocity in affected anterior talofibular ligaments (neutral/stressed, Conclusion: Shear wave elastography noninvasively, conveniently and accurately assesses anterior talofibular ligament quality in chronic ankle instability patients, providing an objective approach for surgical decision-making and rehabilitation monitoring.
