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

An insertion in the promoter of the operon that encodes the molecular chaperone GroE was isolated as an antimutator for stationary-phase or adaptive mutation. The groE operon consists of two genes, groES and groEL; point mutations in either gene conferred the same phenotype, reducing Lac+ adaptive mutation 10- to 20-fold. groE mutant strains had 1/10 the amount of error-prone DNA polymerase IV (Pol IV). In recG+ strains, the reduction in Pol IV was sufficient to account for their low rate of adaptive mutation, but in recG mutant strains, a deficiency of GroE had some additional effect on adaptive mutation. Pol IV is induced as part of the SOS response, but the effect of GroE on Pol IV was independent of LexA. We were unable to show that GroE interacts directly with Pol IV, suggesting that GroE may act indirectly. Together with previous results, these findings indicate that Pol IV is a component of several cellular stress responses.
