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

Since its cloning in 1995, missense point mutations in presenilin I (PS-I) have been shown to be responsible for greater than 70% of the cases of early onset familial Alzheimer's disease (EOFAD), which can affect individuals as early as age 18. PS-I is known to be a component of gamma-secretase, the enzyme responsible for cleavage of the amyloid precursor protein (APP) into 42 amino acid peptides that aggregate to form the plaques surrounding neurons of Alzheimer's patients. It has recently been hypothesized that wild-type (wt) PS-I contains an autoinhibitory module that prevents gamma-secretase cleavage of the APP, while pathogenic PS-I point mutants lack a structure necessary for this inhibition. In this work, spectroscopic data is presented that does not correlate structure or stability of the proposed PS-I autoinhibitory module with pathogenicity.
