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

The H1N1 virus commonly causes symptoms such as fever, cough, sore throat, which have a self-limited course in most cases. Neurological complications are rare, especially in adults. This case illustrates H1N1-associated acute leukoencephalopathy in a young adult with a favorable outcome and no lasting neurological deficits. The initial presentation included fever, sore throat, and myalgia, evolving into neurological symptoms, including dysarthria, nystagmus, and left-sided motor weakness. Comprehensive laboratory tests ruled out common bacterial, viral, or autoimmune causes, while MRI findings suggested acute leukoencephalopathy of infectious or toxic etiology. Although the urine toxicology screen showed traces of phenol, clinical evidence did not correlate with toxic exposure and pointed towards an infectious origin. A throat swab for Influenza/H1N1 PCR confirmed the diagnosis. Treatment with oseltamivir and methylprednisolone led to symptomatic improvement with no sequelae.
