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

abstractA young woman presented with acute-onset hypersomnia. Due to the acute onset, the possibility of secondary cause was considered. Magnetic resonance imaging of the brain was showing involvement of deep gray structures surrounding the third ventricle such as thalamus, hypothalamus, and caudate nucleus with true diffusion restriction. Differentials of vasculitic infarct or inflammatory cause were considered. Among inflammatory causes, neuromyelitis optica spectrum disorder (NMOSD) was considered due to predominant diencephalic involvement. Serum aquaporin-4 immunoglobulin G was positive. No other NMOSD core criteria fulfilling finding was there. Only hypersomnia presentation of NMOSD is uncommon. It should be considered in an acute hypersomnia patient as it is reversible with effective treatment.
