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

aimThe ε4 allele of apolipoprotein E gene (APOE) is a well-known risk factor of late-onset Alzheimer's disease. However, little is known why this variant confers a risk for Alzheimer's disease. The aim of this study was to examine the influence of the APOE genotype on cerebrospinal fluid (CSF) protein levels.

methodsThe present study performed a secondary analysis on our previously generated database to compare the CSF levels of 1128 proteins between APOE-ε4 carriers (28 subjects) and noncarriers (104 subjects). All subjects were physically healthy Japanese individuals without dementia.

resultsCSF levels of apoE2, apoE3, and apoE4 were significantly higher (all nominal P < 10 × 10

conclusionsOur findings indicate the possible roles of apoE and TNF-α in the pathogenesis of APOE-ε4-associated Alzheimer's disease.
