The coracoglenoid notch: anatomy and clinical significance.

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
introductionThe superior surface of the anatomical neck is presented in the classification of scapular fractures as a 2-cm-long structure, which does not correspond to reality. This issue has not yet been adequately addressed in the literature. The aim of the study was to assess the variability of a notch between the upper rim of the glenoid and the coracoid base, the so-called coracoglenoid notch (CGN), and its clinical significance. MATERIALS AND
methodsThe study was based on the examination of 204 dry bone specimens of adult scapulae (92 male and 112 female). We have determined quantitative criteria for the evaluation of the CGN type, measuring the offset of anatomical neck using a digital caliper. The findings were compared with 3D CT reconstructions of fractures of the scapular anatomical neck.
resultsThree basic types of CGN have been identified: type A-a well-developed notch in 31%, type B-a shallow notch in 53% and type C-an absent notch in 16%. No significant difference in CGN was found between the sexes, or between the right and left sides. When compared with our six cases of the anatomical neck fracture of the scapula, two patients displayed CGN type A and type B, respectively; but in four patients, it was impossible to distinguish between types A and B.
conclusionThe study has documented a high variability of CGN. Its presentation in the classification schemes does not correspond to anatomical reality. The presence of a deep, or shallow, notch may constitute an anatomical predisposition to a fracture of the anatomical neck.
