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: Aneurysmal bone cysts (ABCs) are benign yet locally aggressive lesions that can cause significant bone destruction. Involvement of the coracoid process is exceedingly rare, and the diagnosis is particularly challenging due to its atypical presentation. Case Presentation: We report the case of a 37-year-old male with right shoulder pain initially attributed to calcific tendinitis. Advanced imaging incidentally revealed an asymptomatic ABC of the coracoid process. Surgical management involved intralesional curettage and cavity filling with a biphasic calcium sulfate-hydroxyapatite bone graft substitute. Histopathological analysis confirmed the diagnosis of a benign ABC. Postoperative recovery was uneventful, and at 1-year follow-up, the patient was asymptomatic with full shoulder function. Follow-up CT imaging showed no evidence of recurrence and resolution of the initial calcific tendinitis. Conclusion: This case highlights the importance of advanced imaging in atypical shoulder pain and demonstrates that biphasic bone graft substitutes offer a safe and effective alternative to traditional bone grafting in the treatment of ABCs, even in rare anatomical locations. Further research is needed to validate long-term outcomes and establish standardized treatment protocols.
