Hemangiopericytoma: collision with meningioma and recurrence.
Article in Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Intracranial hemangiopericytomas are a rare type of primary brain tumor, representing only about 0.5% of all primary brain tumors. Even more rare is the co-existence of two juxtaposed primary brain tumors, termed a "collision" tumor. This report provides the first documentation in the literature of a hemangiopericytoma colliding with a meningioma, and recurring after treatment with gross total resection. Surgical samples were fully evaluated with hematoxylin and eosin and reticulin staining, as well as immunohistochemical analysis. Results were classically representative of a hemangiopericytoma (World Health Organization grade II) and of a meningioma (World Health Organization grade I). This report of a unique collision tumor not only augments the repertoire of collision tumor combinations described in literature but also provides follow-up on the clinical outcome of the patient, thereby raising clinically relevant issues ranging from presentation to treatment paradigms.
