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: Arthroscopic surgical takedown and repair of symptomatic partial-thickness rotator cuff tears are commonly undertaken. An alternative approach is the use of a bioinductive collagen implant to augment the rotator cuff tear. Purpose: To investigate early function and rotator cuff tendon integrity in patients undergoing arthroscopic bioinductive collagen implant augmentation (REG group) versus rotator cuff takedown and repair (RCR group) for high-grade partial-thickness rotator cuff tears. Study Design: Randomized controlled clinical trial; Level of evidence, 2. Methods: Patients 35 to 75 years of age with symptoms >3 months and unresponsive to nonoperative treatment, with high-grade partial-thickness rotator cuff tears confirmed on 3-T magnetic resonance imaging (MRI), were randomly allocated to RCR or REG groups. Exclusion criteria included previous ipsilateral shoulder surgery, multitendon tears/pathology, and concomitant surgery including labral repair, long head of biceps tenodesis, or chondroplasty/microfracture. Patients were assessed preoperatively and at 6 weeks as well as 3, 6, and 12 months postoperatively. The primary study outcome was the Western Ontario Rotator Cuff Index (WORC) at 3 months after surgery. Secondary outcomes included the American Shoulder and Elbow Surgeons (ASES) and Constant scores, and the time taken to return to work and activities of daily living (ADLs). MRI-based rotator cuff repair integrity was assessed using the Sugaya grading system. Results: This study recruited 41 patients (REG n = 21; RCR n = 20). No group differences ( Conclusion: For symptomatic high-grade partial-thickness rotator cuff tears, bioinductive collagen implant augmentation versus standard rotator cuff repair demonstrated improved early function with equivalent MRI-based healing rates. Registration: Australian New Zealand Clinical Trials Register (ACTRN12620000926932p).
