The rcbA gene product reduces spontaneous and induced chromosome breaks in Escherichia coli.
Article in Journal of bacteriology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Elevated levels of DnaA cause excessive initiation, which leads to an increased level of double-strand breaks that are proposed to arise when newly formed replication forks collide from behind with stalled or collapsed forks. These double-strand breaks are toxic in mutants that are unable to repair them. Using a multicopy suppressor assay to identify genes that suppress this toxicity, we isolated a plasmid carrying a gene whose function had been unknown. This gene, carried by the cryptic rac prophage, has been named rcbA for its ability to reduce the frequency of chromosome breaks. Our study shows that the colony formation of strains bearing mutations in rep, recG, and rcbA, like recA and recB mutants, is inhibited by an oversupply of DnaA and that a multicopy plasmid carrying rcbA neutralizes this inhibition. These and other results suggest that rcbA helps to maintain the integrity of the bacterial chromosome by lowering the steady-state level of double-strand breaks.
