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

Objective: To describe the clinical, pathological, and therapeutic features of spontaneous rupture of a recurrent intracranial dermoid cyst (IDC), and to summarize relevant dermoid-specific literature. Methods: We report a 38-year-old woman with a clinical history of resection of a left middle and posterior cranial fossa dermoid cyst more than 10 years earlier. She presented with headache and vomiting, and imaging suggested rupture of a recurrent lesion with cerebrospinal fluid (CSF) dissemination. Emergency microsurgical resection assisted by neuroendoscopy was performed. Six months postoperatively, she developed delayed obstructive hydrocephalus, requiring neuroendoscopic fenestration and lesion debridement. A narrative literature review of ruptured intracranial dermoid cysts (IDCs) was performed, with emphasis on lesions, dissemination patterns, hydrocephalus, treatment, and reported outcomes. Results: During the initial emergency surgery, the cyst exhibited paste-like consistency with a thickened capsule. Postoperative pathology confirmed a dermoid cyst. However, disseminated foci remained within the cerebral sulci and ventricles. The second surgery revealed multiple pearl-like lesions within the ventricular system with associated lipid leakage. Following clearance of these lesions, the hydrocephalus resolved. Conclusion: Spontaneous rupture of a recurrent IDC is exceptional and may be followed by extensive ventricular dissemination and delayed hydrocephalus. This necessitates a profound understanding of the associated risks, enhanced follow-up protocols, and timely intervention.
