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) and Parkinson's disease (PD) are the most common causes of dementia and movement disorders in the elderly. While progressive accumulation of oligomeric amyloid-beta protein (Abeta) has been identified as one of the central toxic events in AD leading to synaptic dysfunction, accumulation of alpha-synuclein (alpha-syn) resulting in the formation of oligomers has been linked to PD. Most of the studies in AD have been focused on investigating the role of Abeta and Tau; however, recent studies suggest that alpha-syn might also play a role in the pathogenesis of AD. For example, fragments of alpha-syn can associate with amyloid plaques and Abeta promotes the aggregation of alpha-syn in vivo and worsens the deficits in alpha-syn tg mice. Moreover, alpha-syn has also been shown to accumulate in limbic regions in AD, Down's syndrome, and familial AD cases. Abeta and alpha-syn might directly interact under pathological conditions leading to the formation of toxic oligomers and nanopores that increase intracellular calcium. The interactions between Abeta and alpha-syn might also result in oxidative stress, lysosomal leakage, and mitochondrial dysfunction. Thus, better understanding the steps involved in the process of Abeta and alpha-syn aggregation is important in order to develop intervention strategies that might prevent or reverse the accumulation of toxic proteins in AD.
