1 · What the graph read from it

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.

2 · The registry

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

purposeTo demonstrate that the identification and visualization of the inferior fascicle of the anterior talofibular ligament (ATFLif) by ultrasound is feasible, to describe its sonoanatomy, and to compare the ultrasound anatomy of the superior (ATFLsf) and inferior (ATFLif) fascicles.

methodsSixteen fresh-frozen below-the-knee cadaveric ankles were evaluated. Longitudinal ultrasound scans of the ATFLsf and ATFLif were performed using a high-definition transducer. Anatomical dissection followed to expose the fascicles. The length of each fascicle was measured post-dissection using an analog caliper and compared with the sonographic findings.

resultsUltrasound examination, dissection, and measurements were successfully completed in 16 specimens, with the ATFLif visualized in 14 and analyzed in 11. Measurements showed that the inferior fascicle is shorter than the superior fascicle. The intraclass correlation coefficient (ICC 2,1) between sonographic and post-dissection measurements was 0.9752 (95% CI 0.9128-0.9932), indicating the high reliability of the ultrasound method.

conclusionThe fibers of the ATFLif are visible and identifiable by ultrasound. These findings demonstrate the anatomical feasibility of ultrasound identification of both ATFL fascicles and support their inclusion in the systematic examination of the anterolateral ligament complex of the ankle.
