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

Studies of meningococcal pathogenesis have been severely restricted due to the absence of an adequate animal model. Given the significance of iron in meningococcal pathogenesis, we developed a model of Neisseria meningitidis colonization in outbred adult mice that included daily administration of iron dextran. While receiving iron, the animals were inoculated intranasally with the initial doses of bacterial suspension. Meningococci were recovered from the animals by nasopharyngeal washes. Approximately half of the animals inoculated with 10(7) CFU remained colonized 13 days after the initial bacterial inoculation. The model was further evaluated with genetically defined isogenic serogroup B mutant strains, and the colonization capabilities of the mutants were compared to that of the wild-type parent. A mutant that produces truncated lipooligosaccharide (KDO(2)-lipid A) and a mutant defective in capsule transport were dramatically impaired in colonization. A mutant defective in pilus transport (pilQ) showed moderately impaired colonization. The immunological aspect of the model was also evaluated by challenging mice after immunization with homologous whole-cell meningococci. The immunized mice were protected from colonization of the homologous strain. In this model, long-term meningococcal colonization was maintained, allowing us to study the effects of specific genetic mutation on colonization. In addition, this model allows investigation of the role of active immune response against meningococci.
