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

The so-called aeg-46.5 region of Escherichia coli contains genes whose expression is induced under anaerobic growth conditions in the presence of nitrate or nitrite as the terminal electron acceptor. In this work, we have examined more closely several genes of this cluster, here designated ccmABCDEFGH, that are homologous to two separate Bradyrhizobium japonicum gene clusters required for the biogenesis of c-type cytochromes. A deletion mutant of E. coli which lacked all of these genes was constructed. Maturation of indigenous c-type cytochromes synthesized under anaerobic respiratory conditions, with nitrite, nitrate, or trimethylamine N-oxide as the electron acceptor, was found to be defective in the mutant. The biogenesis of foreign cytochromes, such as the soluble B. japonicum cytochrome c550 and the membrane-bound Bacillus subtilis cytochrome c550, was also investigated. None of these cytochromes was synthesized in its mature form when expressed in the mutant, as opposed to the situation in the wild type. The results suggest that the E. coli ccm gene cluster present in the aeg-46.5 region is required for a general pathway involved in cytochrome c maturation.
