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

In bacteria, regulatory networks controlling the adaptation of gene expression in response to stress are frequently complemented by base-pairing small regulatory RNAs (sRNAs) that act at the post-transcriptional level. While many regulatory circuits governing stress resilience have been studied in the model bacterium Caulobacter crescentus, only a small fraction of its diverse sRNA repertoire has been characterized. In this study, we globally identify interacting RNA-RNA pairs associated with the major RNA-binding protein Hfq in C. crescentus. In addition to numerous connections between sRNAs and mRNAs, we also recover RNA-RNA pairs consisting of two non-coding transcripts. Our results indicate that the sRNA CrfA acts as a sponge to inactivate a family of four conserved sRNAs, SisA-D. When induced by carbon starvation, CrfA redirects gene expression towards the utilization of distinct energy sources, and loss of the RNA sponge is linked to a severe growth defect in environments with fluctuating nutrient availability.
