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

Neurodegenerative diseases, the most common among them Alzheimer's disease (AD) and Lewy body disease (LBD), are a group of progressive incurable illnesses. In both AD and LBD, abundant evidence points to the synapse as the critical and early focus of pathological changes. Here we present a method for the isolation and flow cytometric analysis of synaptosomes prepared from postmortem human brain tissue, which we also applied to animal models, including mice and nonhuman primates. The use of flow cytometry for analysis allows for relatively fast and efficient examination of thousands of synaptosome particles in a matter of minutes, and also makes it possible to use crude, rather than purified, synaptosomal preparation, thus conserving tissue resources. We have applied this method to study synaptic alteration in several brain regions in human research participants and animal models.
