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
purposeThe treatment of massive anterior L-shaped rotator cuff tears (RCTs) remains challenging. This study focused on restoration of humeral head coverage by superiorly repositioning the rotator interval tissue. The study aimed (1) to present the short-term clinical and radiological outcomes of arthroscopic partial repair combined with rotator interval shift and (2) to identify risk factors associated with failure in restoring superior humeral head coverage.
methodA retrospective review was conducted on arthroscopic rotator cuff repairs performed by a single surgeon between January 2018 and December 2022. Patients with irreparable anterior L-shaped tears who underwent partial repair and rotator interval shift and had a follow-up of 2 years were included. The measured outcomes included range of motion, pain, and functional scores. Humeral head coverage was evaluated using magnetic resonance imaging (MRI) at 6 months postoperation, and patients were classified as either healed or having a retear. Logistic regression analysis was conducted to identify factors associated with retears.
resultsThe study included 45 patients (19 men and 26 women) with an average age of 66.53 ± 6.70 years. After 2 years, significant improvements were observed in forward elevation (from 77.73 ± 40.96 to 156.11 ± 25.89), abduction (from 82.89 ± 43.78 to 161.33 ± 22.90), American Shoulder and Elbow Surgeons scores (from 43.24 ± 15.77 to 83.16 ± 10.27), and Constant-Murley scores (from 44.98 ± 15.76 to 86.38 ± 10.02; all p < 0.001). Visual analog scale pain scores also decreased (from 7.09 ± 2.35 to 1.29 ± 1.70). MRI results at 6 months showed that 30 of 45 patients (66.7%) had healed, while the retear rate was 33.3%. The acromiohumeral interval (AHI) was identified as the only factor significantly associated with retear. The odds ratio for predicting retear in patients with a preoperative AHI of < 5.0 mm was 5.50. (95% CI: 1.43-21.10, p = 0.013).
conclusionArthroscopic partial repair combined with rotator interval shift is an effective treatment option for irreparable anterior L-shaped RCTs, demonstrating favorable short-term clinical and radiological outcomes. However, patients with a preoperative AHI of less than 5 mm are at greater risk of retear, potentially leading to reduced postoperative range of motion. LEVEL OF EVIDENCE: Level IV, case series.
