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

backgroundChronic subdural hematomas (CSDHs) mainly occur in elderly people and usually develop after minor head injuries. CSDH can be cured by a relatively simple burr hole surgery. Rarely reported, hemorrhagic postsurgical complications include subarachnoid, intracerebral, intraventricular, and remote cerebellar hemorrhages. The causes of such uncommon complications are difficult to explain and remain poorly understood. CASE DESCRIPTION: We report the case study of an 89-year-old man with CSDH who presented with the right hemiparesis. He underwent burr hole surgery with a closed-drainage system. A computed tomography (CT) scan conducted the following day demonstrated an acute intraventricular hemorrhage and hyperperfusion of the ipsilateral hemisphere.

conclusionThis is a rare case of an acute hematoma in the ventricle following drainage of a CSDH. The likely mechanism of this intraventricular hemorrhage could be that the drainage of the hematoma produced a movement of the ventricle and hemisphere accompanied by hyperperfusion.
