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

Background: Brain abscess formation at the site of intracerebral hemorrhage (ICH) is extremely rare, particularly in association with anaerobic pathogens, such as Case Description: An 86-year-old woman presented with right parieto-occipital ICH accompanied by systemic inflammatory signs. Abdominal computed tomography performed at admission revealed findings consistent with sigmoid diverticulitis. Despite initial conservative management, the patient developed bacterial meningitis due to Conclusion: This case suggests that hematogenous dissemination from an intra-abdominal infection may seed injured brain tissue in the early phase after hemorrhage. Disruption of the blood-brain barrier and the relatively avascular, anaerobic environment of a hematoma may predispose patients to abscess formation. In patients with ICH, persistent fever and progressive neurological deterioration despite antimicrobial therapy should prompt consideration of contrast-enhanced neuroimaging to evaluate possible intracranial infectious complications.
