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: Subcoracoid cysts (ScCs) are often associated with rotator cuff tears, but their relationship with rotator cuff retears remains unclear. Purpose: To investigate the correlation between ScCs and retears in patients having undergone arthroscopic rotator cuff repair. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective analysis was conducted on patients who underwent arthroscopic rotator cuff repair from November 2016 to March 2022. Patients with Patte stage 1 or 2 tears were included. Preoperative magnetic resonance imaging (MRI) assessed subscapularis and supraspinatus tendons, biceps pulley, and ScC volume. Postoperative MRI evaluated the same parameters as preoperative MRI, with the addition of rotator cuff retear assessment. On the basis of preoperative MRI, patients were classified into group A (with cyst) and group B (without cyst). According to postoperative MRI, groups were further divided into A1 (without retear), A2 (with retear), B1 (without retear) and B2 (with retear). Postoperative decrease in ScC volume (ScC delta), Sugaya classification, and Constant score were compared. Results: The study included 109 patients: 69 in group A (A1 = 40, A2 = 29) and 40 in group B (B1 = 35, B2 = 5). The retear rate was significantly higher in group A (34.8%) than in group B (12.5%) ( Conclusion: For the patients with ScCs detected on preoperative MRI scans, preserved tendon integrity after rotator cuff repair was associated with a reduction in ScC volume. This reduction was evident on postoperative MRI scans when compared with preoperative measurements. Conversely, compromised tendon integrity did not lead to a significant reduction in ScC volume after surgery, potentially suggesting cyst reformation. Therefore, the postoperative identification of an ScC may indirectly indicate rotator cuff retear.
