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

Regulation of the Escherichia coli stationary-phase sigma factor RpoS is complex and occurs at multiple levels in response to different environmental stresses. One protein that reduces RpoS levels is the transcription factor LrhA, a global regulator of flagellar synthesis. Here we clarify the mechanism of this repression and provide insight into the signaling pathways that feed into this regulation. We show that LrhA represses RpoS at the level of translation in a manner that is dependent on the small RNA (sRNA) chaperone Hfq. Although LrhA also represses the transcription of the sRNA RprA, its regulation of RpoS mainly occurs independently of RprA. To better understand the physiological signals affecting this pathway, a transposon mutagenesis screen was carried out to find factors affecting LrhA activity levels. The RcsCDB phosphorelay system, a cell envelope stress-sensing pathway, was found to repress lrhA synthesis. In addition, mutations in the gene encoding the DNA motor protein FtsK induce lrhA synthesis, which may explain why such strains fail to accumulate RpoS in stationary phase.
