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 atypical, Stx2-producing, pathogenic Escherichia coli O157:H(-) strain has been isolated with increasing frequency from hemolytic uremic syndrome patients in Germany. The lack of the H7 antigen coupled with the strain's ability to ferment sorbitol and express beta-glucuronidase have complicated its detection and identification. In this study, we have determined that the loss of motility in these German sorbitol-fermenting (SF) O157 strains is due to a 12-bp in-frame deletion in flhC that is required for transcriptional activation of genes involved in flagellum biosynthesis. Either complementation with a functional flhC or repair of this mutation restored H7 antigen expression and motility. PCR analysis of several nonmotile E. coli O157 strains from various geographical sources confirmed that the 12-bp flhC deletion is found only in the cluster of German SF O157 strains, providing a potentially useful marker by which these atypical strains can be identified. The loss of motility via mutations in the flhDC operon that we observed in the German SF O157 strains is consistent with a similar phenomenon currently observed in a significant subset of other important gram-negative pathogens.
