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
Aims: The Latarjet procedure is the treatment of choice for patients who have recurrent anterior shoulder instability with glenoid bone loss. However, the stabilizing effect of the Latarjet procedure in patients is sparsely described. The aim of this study was to evaluate the glenohumeral joint (GHJ) kinematics during an apprehension-relocation test in patients with anterior shoulder instability before and after their Latarjet procedure, and in comparison with their contralateral healthy shoulder. Methods: A total of 20 patients scheduled for the Latarjet procedure were enrolled. The patients were examined preoperatively with bilateral radiostereometric analysis (RSA) and one year after surgery on the operated shoulder with an apprehension-relocation test. Bone models were obtained from CT scans and aligned with the RSA images. The GHJ kinematics was evaluated with two methods: the humeral head centre location relative to the glenoid centre, and the GHJ contact point relative to the glenoid centre. Results: No difference in GHJ kinematics was found between the healthy and the postoperative GHJ. Compared with the preoperative injured shoulder, the postoperative mean (95% CI) humeral head centre was 0.8 mm (0.1 to 1.4) more superior and 0.7 mm (-0.1. to 1.4) more posterior during the apprehension test, and 0.5 mm (0.0 to 1.1) more posterior during the relocation test. The postoperative contact point was posterior to the coracoid bone block and 0.9 mm (-0.2 to 2.0) more posterior than in the preoperative injured shoulder during the apprehension test. The articulating area of the coracoid bone block was decreased by 63.9% (75.5 to 114.6) one year after surgery. Conclusion: The Latarjet procedure restored the humeral head centre location posterior and superior, and the contact point posterior, to the coracoid bone block. This suggests that the stabilizing effect of the GHJ following the Latarjet procedure is primarily due to the conjoined tendon rather than the coracoid bone block itself.
