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
Neoplastic cerebral aneurysms (NCAs) are rare. This study reported a case of an NCA secondary to a poorly differentiated carcinoma of the parotid gland. An 84-year-old Japanese woman undergoing treatment for parotid gland cancer was admitted to our hospital with headache and progressive loss of consciousness. Based on computed tomography (CT) and CT angiography (CTA), a diagnosis of subarachnoid hemorrhage due to rupture of a left posterior inferior cerebellar artery aneurysm was made, and emergency aneurysmectomy was performed. Pathological examination of the resected aneurysm showed an NCA secondary to parotid carcinoma. After the aneurysmectomy, her condition stabilized; however, 33 days later, the patient developed an intracerebral hemorrhage, and a new aneurysm was confirmed in the right middle cerebral artery. To the best of our knowledge, there have been no previous reports on cases of NCAs secondary to parotid carcinoma. The pathology and clinical course strongly suggest that NCAs derived from malignant tumors may have an aggressive course.
