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: The present study primarily aimed to investigate whether preoperative pain associated with rotator cuff tears correlates with the severity of synovitis in the rotator interval (RI) on arthroscopic findings retrospectively. Methods: Between July 2017 and December 2022, 131 shoulders with arthroscopic rotator cuff repair were retrospectively investigated. The pain domain of the preoperative Constant Score and Shoulder36 were used to assess preoperative pain. Two examiners confirmed the degree of synovitis of RI in the arthroscopic findings. Results: The mean patient age was 68.9 years. Synovitis in the RI was found in 118 shoulders (94%) assessed by arthroscopy. The pain domain of the Constant Score significantly correlated with synovitis in the RI assessed by arthroscopic findings ( Conclusion: The preoperative pain associated with rotator cuff tears significantly correlated with synovitis severity in the RI assessed by AS findings, highlighting the role of synovitis as a potential contributor to pain in patients with rotator cuff tears.
