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

Microbial infections are a global health problem, particularly as microbes are continually developing resistance to antimicrobial treatments. An effective and reliable method for testing the virulence of different microbial pathogens is therefore a useful research tool. This protocol describes how the chicken embryo can be used as a trustworthy, inexpensive, ethically desirable and quickly accessible model to assess the virulence of the human bacterial pathogen Listeria monocytogenes, which can also be extended to other microbial pathogens. We provide a step-by-step protocol and figures and videos detailing the method, including egg handling, infection strategies, pathogenicity screening and isolation of infected organs. From the start of incubation of the fertilized eggs, the protocol takes <4 weeks to complete, with the infection part taking only 3 d. We discuss the appropriate controls to use and potential adjustments needed for adapting the protocol for other microbial pathogens.
