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 biomechanics of reverse shoulder arthroplasty (RSA) rely on deltoid function. The center of rotation of the glenohumeral joint in RSA is more medial and distal when compared to the native joint, and proper soft-tissue tensioning is essential to achieve a stable joint with a good range of motion (ROM). The current RSA systems on the market allow for various placements of humeral and glenoid components (lateralized, medialized, distalized). No post-operative radiographic parameters currently consider the glenoid and humeral components' position separately. The aims of this study are to (1) measure glenoid and humeral component angles specific to different implants and (2) to investigate whether these angles correlate with clinical outcomes. Methods: A retrospective analysis of 74 patients who underwent reverse shoulder prosthesis between 2018 and 2022 was performed. Different subtypes of RSA prosthesis were identified (medialized glenoid/lateralized humerus, lateralized glenoid/medialized humerus, and lateralized glenoid/lateralized humerus). Angle measurements were defined to determine the lateralization and distalization of each component in true anteroposterior radiographs (Grashey view) of the shoulder. The clinical results were collected, including a Simple Shoulder est, Single Assessment Numeric Evaluation, and Constant score. Results: All angles showed excellent intra-rater and inter-rater agreement. No correlation was found between ROM and post-operative radiographic measurements, and there were no significant differences between the different RSA subtypes in clinical outcomes. Conclusion: The main objectives to be met are the post-operative scores, ROM, and patient satisfaction after RSA; however, there are still no reliable measures in post-operative radiographs that correlate with clinical outcomes. The current angles obtained on post-operative radiographs allow us to assess the prosthesis's placement degree due to each of the components but not to predict ROM or clinical outcomes.
