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

Purpose: To compare revision rates and functional outcomes between patients who underwent staged versus simultaneous bilateral rotator cuff repair (RCR). Methods: This systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines with no institutional review board approval or funding required. The PubMed, SportDiscus, and Ovid Medline databases were queried to identify original research studies evaluating preoperative characteristics and postoperative outcomes of staged or simultaneous RCR. The following search algorithm was used: ((Bilateral) OR (simultaneous) OR (Staged)) AND (rotator cuff repair). Demographics including the number of male and female patients, age, type of surgical intervention, time between staged surgery, and surgical indication were collected. Variables of interest included pre- and postoperative shoulder pain and functional scores, as well as retear, reoperation, revision, complications, and their rates of occurrence. Results: Overall, 594 studies were screened, and 8 studies were included in this systematic review. In total, 11,188 patients (97.5%) underwent staged repair and 286 (2.5%) underwent simultaneous repair. Delaying staged surgery by more than 2 years also had decreased surgical complications such as conversion to reverse total shoulder arthroplasty, postoperative infection, venous thromboembolism, and emergency department visits when compared with simultaneous RCR ( Conclusions: Staged RCR has superior functional outcomes, decreased surgical complications, as well as lower revision rates than simultaneous RCR. Level of Evidence: Level IV, systematic review of Level II-IV studies.
