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
Background: The objectives of the present study were to perform a three-dimensional morphometric analysis of global scapular shape in 500 individuals using homologous modeling and to examine sex-related and generational differences in global scapular shape. Methods: Computed tomography images of the scapulae of 500 individuals were obtained. A homologous model of the scapula, comprising 19,563 vertices, was created based on 40 landmarks. Principal component analysis of the three-dimensional coordinates of all vertices was performed. The morphological variation represented by each principal component (PC) was interpreted based on the virtual shape of each loading score, a 2-way analysis of variance of PC scores was conducted to assess sex-related and generational differences. Results: Men had the following characteristics compared with women, the scapular body was longitudinally longer than transversely (PC1); the lateral morphology was posteriorly inclined, and the scapular body was anteriorly inclined (PC2); the acromion was anteriorly oriented, and anteroposterior diameters of the scapular body and supraspinous fossa were increased (PC5); the acromion and coracoid process were anteriorly oriented, and the width of the scapular body was increased medially and laterally (PC6). The older age group showed a tendency toward having a posterior tilt of the lateral morphology and an anterior tilt of the scapular body (PC2), a medial orientation of the acromion, and increased anteroposterior diameter of the supraspinatus fossa (PC3) compared with the younger age group. Conclusion: We observed several variations in the global shape of the scapula. Sex-related and generational differences in global scapular shape were clarified. These differences may be considered when analyzing scapular morphology.
