1 · What the graph read from it

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.

2 · The registry

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: Rotator cuff tears can result in pain which can be debilitating. The etiology of failed repair or retears is multifactorial. Multiple risks factors were proposed, with critical shoulder angle (CSA) being one of the factors of emerging interest. Other radiological parameters including glenoid inclination (GI), lateral acromial angle (LAA), and acromial index (AI) were also suggested for a possible correlation. Methods: A retrospective review of 397 rotator cuff repairs on January 1, 2000 to December 31, 2023 recruited from two major hospitals was carried out. Primary outcome measure of radiographic shoulder angles (CSA, GI, LAA, and AI) was measured. Results: There is no statistical difference in radiographic shoulder angles measured in the rotator cuff retear group and the no retear group. Retear patients were more likely to have Goutallier grade 3 and 4 (p = 0.01). Goutallier grade 4 was the potential predictor of retear regardless of sex (Odds ratio=5.25 (1.38, 20.02); p = 0.02). Conclusion: There is no definite association of rotator cuff retear and radiographic parameters including CSA, GI, LAA, and AI in this study.
