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

Introduction The deltoid ligament complex (DLC) confers stability of the ankle joint. This study quantitatively analyzes the morphometry of the DLC in the Southeast Asian population, highlighting anatomical variations relevant to surgical procedures. Methodology Seven embalmed amputated limbs were dissected. The width and length of the superficial and deep layers with their corresponding bands were measured using a metric ruler. Results The mean width of the superficial layer of the DLC was 20.43 + 2.72 mm at the origin, 20.00 + 1.07 mm at midway, and 15.29 + 1.28 mm at insertion. The tibionavicular ligament (TNL), tibiocalcaneal ligament (TCL), deep posterior tibiotalar ligament (dPTTL), and the deep anterior tibiotalar ligament (dATTL) were present in all specimens. In the superficial layer, the mean length of the TNL and TCL was 38.57 + 3.58 mm and 34.29 + 6.47 mm, respectively. In the deep layer, the mean length of the dPTTL and dATTL was 18.71 + 1.83 mm and 20.29 + 2.31 mm, respectively. Conclusion While the prevalence of the components of the DLC varies widely across the literature, it was present in all specimens of our study. The longest and shortest bands of the DLC were the TNL and dPTTL, respectively, concurring with current literature. However, the mean length of TCL, dPTTL, and dATTL in the Southeast Asian population appeared to be longer than that reported in a meta-analysis of European cadaveric studies. Knowledge of the morphology and anatomical variations of each component of the DLC in the Southeast Asian population is crucial to improve surgical management of medial ankle instability.
