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

Alzheimer's disease (AD) is characterized by synaptic dysfunction and cardinal neuropathological features including amyloid plaques and neurofibrillary tangles. Soluble amyloid-beta (Abeta) can suppress synaptic activities by interacting with alpha7 nicotinic acetylcholine receptors (alpha7nAChRs). Here, we show that alpha7nAChR and NMDA glutamatergic receptor (NMDAR) activities are severely compromised in synaptosomes prepared from AD and Abeta(1-42) (Abeta42)-exposed control frontal cortex slices from postmortem tissue. Whereas Abeta(12-28) prevents Abeta42 from binding to alpha7nAChRs, 2-[2-(4-bromophenyl)-2-oxoethyl]-1-methyl pyridinium (S 24795), a novel alpha7nAChR partial agonist, facilitates release of Abeta42 from Abeta42-alpha7nAChR and -Abeta42 complexes. S 24795 interacts with alpha7nAChR and Abeta(15-20) region of the Abeta42 to enable partial recovery of the alpha7nAChR and NMDAR channel function. These findings suggest that the Abeta-alpha7nAChR interaction may be an upstream pathogenic event in AD and demonstrate that some recovery of neuronal channel activities may be achieved in AD brains by removing Abeta from alpha7nAChRs.
