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

The biogenesis of the amyloid-beta peptide (Abeta) is a central issue in Alzheimer's disease (AD) research. Abeta is produced by beta- and gamma-secretases from the amyloid-beta protein precursor (AbetaPP). These proteases are targets for the development of therapeutic compounds to downregulate Abeta production. gamma-secretase has received more attention 1) because it generates the C-terminus of Abeta, which is important in the pathogenesis of AD because the longer Abeta species are more amyloidogenic, and 2) because it cleaves AbetaPP within its transmembrane domain. In the understanding the mechanism of gamma-secretase cleavage, three major cleavage sites have been identified, namely, gamma-cleavage site at Abeta(40/42), zeta-cleavage site at Abeta(46), and epsilon-cleavage site at Abeta(49). Moreover, the novel finding that some of the known gamma-secretase inhibitors inhibit the formation of secreted Abeta(40) and Abeta(42), but cause an intracellular accumulation of long Abeta(46), provided information extremely important for the development of strategies aimed at the design of gamma-secretase inhibitors to prevent and treat AD. In addition, it has been established that the C-terminus of Abeta is generated by a series of sequential cleavages: first, epsilon-cleavage, followed by zeta-cleavage and finally by gamma-cleavage, commencing from the membrane boundary to the middle of the AbetaPP membrane domain.
