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

backgroundThe primary aim of this study was to quantitatively analysis the acetabular morphological feature and 2D/3D coverage of the Crowe IV DDH hip, dividing into subgroups by the false acetabulum. The secondary aim was to propose a 3D bone mapping to determine acetabular bone defect analysis from the perspective of the implanted simulation.

methodsA total of 53 Crowe IV hips (27 hips without the false acetabulum in IVa group and 26 hips in IVb group) and 40 normal hips met the inclusion criteria and were retrospectively evaluated. Firstly, the anatomical size and volume of the acetabulum were measured quantitatively. Secondly, through the simulated implantation, morphological assessments of the true acetabulum included Cup-CE, Cup-Sharp, acetabular anteversion angle, and thickness of the medial wall. Last, Acetabular sector angles (ASAs) and the component coverage ratio were measured to provide coverage indices. Further, 3D bone mapping visualization was applied to determine the uncovered component portion distribution.

resultsThe anatomic shape and volume of the acetabular triangle were significantly smaller in Crowe IV hips. At the level of the acetabular component center, IVb acetabula were found to be more anteverted and abductive, with smaller Cup-CE and larger Cup-Sharp angles. The coverage sector angles in Crowe IVa hips were larger in the anterosuperior and superior direction, while smaller in the posterosuperior and posterior direction, with no subgroup difference in total component coverage. Both 3D bone mapping and correlation analysis reveal that posterosuperior and posterior bone stock is highly associated with the component coverage.

conclusionWith the presence of the false acetabulum, there existed acetabular anteversion and segmental coverage distinctions between subgroups. During the acetabular reconstruction, management of posterosuperior and posterior bone stock was important for ideal component coverage.
