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

Microcolony formation is one of the initial steps in biofilm development, and in enteropathogenic Escherichia coli (EPEC) it is mediated by several adhesins, including the bundle-forming pilus (BFP) and the EspA filament. Here we report that EPEC forms biofilms on plastic under static conditions and a flowthrough continuous culture system. The abilities of several EPEC isogenic mutants to form biofilms were assessed. Adhesins such as BFP and EspA, important in microcolony formation on epithelial cells, are also involved in bacterial aggregation during biofilm formation on abiotic surfaces. Mutants that do not express BFP or EspA form more-diffuse biofilms than does the wild type. We also determined, using gfp transcriptional fusions, that, consistent with the role of these adhesins in biofilms, the genes encoding BFP and EspA are expressed during biofilm formation. Finally, expression of espA is controlled by a quorum-sensing (QS) regulatory mechanism, and the EPEC qseA QS mutant also forms altered biofilms, suggesting that this signaling mechanism plays an important role in EPEC biofilm development. Taken together, these studies allowed us to propose a model of EPEC biofilm formation.
