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

When two different strains of swarming Proteus mirabilis encounter one another on an agar plate, swarming ceases and a visible line of demarcation forms. This boundary region is known as the Dienes line and is associated with the formation of rounded cells. While the Dienes line appears to be the product of distinction between self and nonself, many aspects of its formation and function are unclear. In this work, we studied Dienes line formation using clinical isolates labeled with fluorescent proteins. We show that round cells in the Dienes line originate exclusively from one of the swarms involved and that these round cells have decreased viability. In this sense one of the swarms involved is dominant over the other. Close cell proximity is required for Dienes line formation, and when strains initiate swarming in close proximity, the dominant Dienes type has a significant competitive advantage. When one strain is killed by UV irradiation, a Dienes line does not form. Killing of the dominant strain limits the induction of round cells. We suggest that both strains are actively involved in boundary formation and that round cell formation is the result of a short-range killing mechanism that mediates a competitive advantage, an advantage highly specific to the swarming state. Dienes line formation has implications for the physiology of swarming and social recognition in bacteria.
