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

Arachnoid cysts have been previously reported in SPG4-related disorders1. AlthoughSPG4 and SPG7 are both members of the ATPases Associated with diverse cellularActivities (AAA) protein family2, arachnoid cysts have not been heretofore reported inSPG7-related disorders. We identified arachnoid cysts in 2 unrelated patients withSPG7-related disorders and hereby present the neuroimages (Fig. 1A and B) fromone of the patients. We report retro-cerebellar arachnoid cyst in a 45-year-old man witha novel heterozygous germline SPG7 pathogenic splice site variant [NM_003119.4,c.861+1G>C], which was detected on genome sequencing in the context of concernsfor tremor, hyperreflexia, neuropathy, poor coordination, hyperlipidemia andhypertension.
