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: Arthroscopically assisted posterior latissimus dorsi (LD) tendon transfer has shown promise in patients with posterior superior rotator cuff tears (PSRCTs). Body mass index (BMI), a modifiable patient factor, may influence outcomes in rotator cuff surgeries. However, its impact on outcomes following arthroscopically assisted LD transfer remains underexplored. This study aims to assess the relationship between BMI and clinical outcomes in patients undergoing LD transfer for PSRCTs. Methods: A retrospective review of patients who underwent arthroscopically assisted posterior LD transfer with a minimum of 5 years of follow-up was conducted. Clinical outcomes, including pain (visual analog scale), patient-reported outcome measures, and range of motion (ROM), were assessed preoperatively and at final follow-up. Patients were divided into 2 groups based on BMI (≥26.2 and <26.2). Also, univariable and multivariable regression models were used to evaluate associations between BMI and clinical outcomes. Results: A total of 57 patients were included, with a mean follow-up of 76.7 ± 7.2 months (range, 69-92), and a mean age of 63.2 ± 8.6 years (range, 43-80). The average BMI was 26.2. Significant improvements were observed in all clinical measures, including pain; patient-reported outcome measures including Simple Shoulder Test, Subjective Shoulder Value, Activities of Daily Living External Rotation score, and the American Shoulder and Elbow Surgeons score; and ROM, all Conclusion: Arthroscopically assisted posterior LD tendon transfer for PSRCTs leads to substantial improvements in pain, function, and ROM. No significant differences were observed between above-average and below-average BMI groups, and BMI was not correlated with clinical improvements. These findings suggest that BMI may not influence the effectiveness of posterior LD transfer.
