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

Gram-negative bacteria release outer membrane vesicles (OMVs) that deliver various molecules, including virulence factors, to interact with their host. Recent studies have suggested that OMVs may also serve as carriers for RNAs, particularly small regulatory noncoding RNAs (sRNAs). For these RNAs to function effectively, they typically require a protein cofactor, Hfq, known as an RNA chaperone. In previous work, using molecular imaging, Circular Dichroism CD, and InfraRed FTIR spectroscopies, we demonstrated that Hfq interacts with the bacterial inner membrane and forms pores, suggesting a possible role in translocating RNA from the cytoplasm to periplasm and then to OMVs. In this study, we expand on our previous findings and provide evidence that RNA molecules bind to the
