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

Brain abscess developing at the site of intracerebral hemorrhage has rarely been reported. We report herein a case of brain abscess following intracerebral hemorrhage that mimicked a chronic encapsulated intracerebral hematoma. An 80-year-old man presented with right hemiparesis caused by a left frontoparietal subcortical intracerebral hemorrhage, which was managed conservatively. During hospitalization, progressive motor aphasia developed. Two weeks after admission, magnetic resonance imaging demonstrated worsening perihematomal edema and ring enhancement along the hematoma margin. Diffusion-weighted imaging demonstrated hyperintensity with heterogeneous restricted diffusion on the apparent diffusion coefficient map. Because there were no systemic signs of infection, chronic encapsulated intracerebral hematoma was initially suspected. However, the neurological and radiological deterioration progressed, prompting neuroendoscopic evacuation of the hematoma cavity. Microbiological examination revealed
