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.
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 present the case of a 69-year-old male patient who presented with progressive neck swelling causing symptoms of dysphonia and dysphagia. Flexible nasendoscopy revealed bruising of the right hemilarynx, hypopharynx and parapharyngeal mucosal consistent with a spontaneous cervical haematoma. After conservative management, the haematoma self-resolved and the source of the haematoma was thought to be a parathyroid adenoma. Surgical excision was completed, and histopathological assessment revealed a parathyroid carcinoma. Spontaneous cervical haematoma can progress to airway obstruction and the initial focus is to observe for any signs of progression and establish a secure airway if required. The subsequent challenge is to establish the origin of the haematoma and as in this case this can be a diagnostic challenge. This case highlights the diagnostic difficulties of spontaneous cervical haematoma, the importance of comprehensive investigation and the possibility of malignancy preoperatively, especially important when complete excision gives the best opportunity for cure.
