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

introductionAnkle sprains are common sports-related injuries, and recurrent sprains may lead to chronic ankle instability (CAI). The mechanical and geometric properties of lateral ankle ligaments are crucial for joint stability. This study investigated how variations in Young’s modulus and thickness of the lateral ankle ligaments influence ankle stability.

methodsA finite element model of the ankle was developed, in which the thickness and Young’s modulus of the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL) were individually varied. Anterior stiffness and inversion stiffness were assessed via simulated anterior drawer and talar tilt tests.

resultsFor the ATFL and PTFL, both anterior and inversion stiffness increased with greater Young’s modulus and ligament thickness. For the CFL, increases in Young’s modulus and thickness only enhanced inversion stiffness. The Young’s modulus–thickness–joint stiffness relationship for the ATFL was best described by a sigmoid-like curve, while those for the CFL and PTFL were best fitted with polynomial curves.

conclusionVariations in Young’s modulus and thickness of the ATFL, CFL, and PTFL significantly affect ankle joint stability. The fitted Young’s modulus–thickness–joint stiffness functions may provide valuable reference data for the clinical diagnosis and treatment of CAI.
