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

backgroundAmebic encephalitis (granulomatous amebic encephalitis, GAE) an extremely rare disease occurring in immunocompromised patients. Presentation and early imaging findings are nonspecific. In GAE, enhancement may or may not be seen on imaging studies despite the presence of an aggressive, necrotizing, parasitic infection. CASE DESCRIPTION: The patient was a 79-year-old man with ill-defined autoimmune hepatitis. He was on mild immunosuppression with 6-MP and low-dose prednisone. He presented with an acute febrile illness and obtundation. Imaging revealed a nonenhancing mass lesion of the frontal lobe. The patient briefly improved on high-dose steroids, then deteriorated again, with repeat imaging showing enlargement of the edematous brain lesion and herniation. The patient underwent craniotomy for evacuation of a necrotic brain lesion. His condition did not improve. Frozen section revealed only necrosis. Permanent pathology revealed GAE caused by Acanthamoeba.

conclusionNeurosurgeons should remain aware of this rare disease. Imaging is variable and may not show enhancement or necrosis despite large areas of parasitic infection.
