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

Rrp1 is the sole c-di-GMP-producing protein (diguanylate cyclase) of Borrelia burgdorferi. To test the hypothesis that Rrp1 regulates critical processes involved in the transmission of spirochetes between ticks and mammals, an rrp1 deletion mutant (B31-Δrrp1) and a strain that constitutively produces elevated levels of Rrp1 (B31-OV) were constructed. The strains were assessed for progression through the enzootic cycle using an Ixodes tick/C3H-HeJ mouse model and tick immersion feeding methods. B31-Δrrp1 infected mice as efficiently as wild type but had altered motility, decreased chemotactic responses to N-acetylglucosamine (NAG) and attenuated ability to disseminate or colonize distal organs. While this strain infected mice, it was not able to survive in ticks. In contrast, B31-OV displayed normal motility patterns and chemotactic responses but was non-infectious in mice. Using immersion feeding techniques, we demonstrate that B31-OV can establish a population in ticks and survive exposure to a natural bloodmeal. The results presented here indicate Rrp1, and by extension, c-di-GMP, are not strictly required for murine infection, but are required for the successful establishment of a productive population of B. burgdorferi in ticks. These analyses provide significant new insight into the genetic regulatory mechanisms of the Lyme disease spirochetes.
