Plasmids in the driving seat: The regulatory RNA Rcd gives plasmid ColE1 control over division and growth of its E. coli host.
Review in Plasmid, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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.
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 by non-coding RNAs was found to be widespread among plasmids and other mobile elements of bacteria well before its ubiquity in the eukaryotic world was suspected. As an increasing number of examples was characterised, a common mechanism began to emerge. Non-coding RNAs, such as CopA and Sok from plasmid R1, or RNAI from ColE1, exerted regulation by refolding the secondary structures of their target RNAs or modifying their translation. One regulatory RNA that seemed to swim against the tide was Rcd, encoded within the multimer resolution site of ColE1. Required for high fidelity maintenance of the plasmid in recombination-proficient hosts, Rcd was found to have a protein target, elevating indole production by stimulating tryptophanase. Rcd production is up-regulated in dimer-containing cells and the consequent increase in indole is part of the response to the rapid accumulation of dimers by over-replication (known as the dimer catastrophe). It is proposed that indole simultaneously inhibits cell division and plasmid replication, stopping the catastrophe and allowing time for the resolution of dimers to monomers. The idea of a plasmid-mediated cell division checkpoint, proposed but then discarded in the 1980s, appears to be enjoying a revival.
