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

Transcription of the Escherichia coli osmB gene is induced by several stress conditions. osmB is expressed from two promoters, osmBp1 and osmBp2. The downstream promoter, osmBp2, is induced after osmotic shock or upon entry into stationary phase in a sigma(S)-dependent manner. The upstream promoter, osmBp1, is independent of sigma(S) and is activated by RcsB, the response regulator of the His-Asp phosphorelay signal transduction system RcsCDB. RcsB is responsible for the induction of osmBp1 following treatment with chlorpromazine. Activation of osmBp1 by RcsB requires a sequence upstream of its -35 element similar to the RcsB binding site consensus, suggesting a direct regulatory role. osmB appears as another example of a multistress-responsive gene whose transcription involves both a sigma(S)-dependent promoter and a second one independent of sigma(S) but controlled by stress-specific transcription factors.
