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

Borrelia burgdorferi, the causative agent of Lyme disease, cycles in nature between a vertebrate host and a tick vector. We demonstrate that B. burgdorferi can utilize several sugars that may be available during persistence in the tick, including trehalose, N-acetylglucosamine (GlcNAc), and chitobiose. The spirochete grows to a higher cell density in trehalose, which is found in tick hemolymph, than in maltose; these two disaccharides differ only in the glycosidic linkage between the glucose monomers. Additionally, B. burgdorferi grows to a higher density in GlcNAc than in the GlcNAc dimer chitobiose, both of which may be available during tick molting. We have also investigated the role of malQ (bb0166), which encodes an amylomaltase, in sugar utilization during the enzootic cycle. In other bacteria, MalQ is involved in utilizing maltodextrins and trehalose, but we show that, unexpectedly, it is not needed for B. burgdorferi to grow in vitro on any of the sugars assayed. In addition, infection of mice by needle inoculation or tick bite, as well as acquisition and maintenance of the spirochete in the tick vector, does not require MalQ.
