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 presence of RNAs in the extracellular milieu has sparked the hypothesis that RNA may play a role in mammalian cell-cell communication. As functional nucleic acids transfer from cell to cell in plants and nematodes, the idea that mammalian cells also transfer functional extracellular RNA (exRNA) is enticing. However, untangling the role of mammalian exRNAs poses considerable experimental challenges. This Review discusses the evidence for and against functional exRNAs in mammals and their proposed roles in health and disease, such as cancer and cardiovascular disease. We conclude with a discussion of the forward-looking prospects for studying the potential of mammalian exRNAs as mediators of cell-cell communication.
