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

Mutations in presenilin (PS) proteins cause familial Alzheimer's disease. We herein tested the hypothesis that the expression levels of PS proteins are differentially affected during healthy aging, in the absence of pathological mutations. We used a preclinical model for aging to identify associations between PS expression and quantitative behavioral parameters for spatial memory and learning and motor function. We identified significant changes of PS protein expression in both cerebellum and forebrain that correlated with the performance in behavioral paradigms for motor function and memory and learning. Overall, PS1 levels were decreased, while PS2 levels were increased in aged mice compared with young controls. Our study presents novel evidence for the differential expression of PS proteins in a nongenetic model for aging, resulting in an overall increase of the PS2 to PS1 ratio. Our findings provide a novel mechanistic basis for molecular and functional changes during normal aging.
