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

Eosinophilic meningitis caused by Angiostrongylus cantonensis is an uncommon disease in Brazil that occurs by ingesting slugs, water or food contaminated with the parasite. Here we report a case of a 64-year-old patient with neck stiffness, headache, fever, and peripheral and cerebrospinal fluid (CSF) eosinophilia, compatible with eosinophilic meningitis. He had a false-positive result for Neisseria meningitides and received unsuccessful treatment with antibiotics. After extensive investigation, DNA and anti-A.cantonensis antibodies were detected and the patient was successfully treated with prednisone and albendazole. Diagnosis of neuroangiostrongyliasis relies on epidemiological data, as well as clinical and laboratory examinations such as detection of antibodies and DNA of the parasite in CSF. Its timely treatment with corticosteroid therapy reduces damage to neural tissues and manages headache.
