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, has a complex genome consisting of a linear chromosome and up to 21 linear and circular plasmids. These plasmids encode numerous proteins critical to the spirochete's infectious cycle and many hypothetical proteins whose functions and requirements are unknown. The conserved linear plasmid lp54 encodes several proteins important for survival in the mouse-tick infectious cycle, but the majority of the proteins are of unknown function and lack homologs outside the borreliae. In this study we adapted the Cre-lox recombination system to create large deletions in the B. burgdorferi genome. Using Cre-lox, we systematically investigated the contribution of 14 adjacent genes on the left arm of lp54 to the overall infectivity of B. burgdorferi. The deletion of the region of lp54 encompassing bba07 to bba14 had no significant effect on the infectious cycle of B. burgdorferi. The deletion of bba01 to bba07 resulted in a slight growth defect but did not significantly affect the ability of B. burgdorferi to complete the infectious cycle. This study demonstrated the utility of the Cre-lox system to efficiently explore gene requirements in B. burgdorferi and surprisingly revealed that a large number of the highly conserved proteins encoded on lp54 are not required to complete the infectious cycle.
