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

Astrocytes are morphologically and functionally linked to neuronal synapses, and can regulate the activity of neural circuits, brain function, and behavior. However, the molecular mechanisms by which astrocytes regulate fundamental biological processes such as sleep are not completely understood. Wu and colleagues show that an increase in calcium signals within the processes of astrocytes of the fruit fly brain can promote sleep by upregulating the expression of a monoamine receptor, TyrRII, which in turn activates sleep promoting neurons via the astrocytic release of an interleukin-1 analog, spatzle. This study provides compelling evidence for a novel molecular mechanism by which increases in astrocytic calcium signals can induce sleep by activating sleep promoting neurons in the fly brain.
