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

We encountered a rare case of venous malformation located in the parapharyngeal space. The 65-year-old female patient did not have any symptoms, and the malformation was discovered incidentally during a clinical survey. Examination of the oral cavity revealed a mass in the left soft palate. Magnetic resonance imaging showed a well-defined mass in the left parapharyngeal space. Fine needle aspiration cytology suggested no malignancy. Four years after the first visit, she underwent surgery for diagnosis and treatment. We safely removed the mass with a rigid videoendoscope trans-orally. No postoperative complications arose, and she was discharged 7 days after the operation. Histopathological examination identified cavernous hemangioma. Venous malformation (cavernous hemangioma) of the parapharyngeal space is very rare, and few cases of removal under a transoral approach using a rigid endoscope with a flexible tip have been reported. This approach is safe and can be recommended for selected tumors of the parapharyngeal space.
