A Method of Transposon Insertion Sequencing in Comprehensively Identifying Vibrio vulnificus Genes Required for Growth in Human Serum.

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.
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
One of the most powerful approaches to detect the loci that enable a pathogen to cause disease is the creation of a high-density transposon mutant library by transposon insertion sequencing (TIS) and the screening of the library using an adequate in vivo and/or ex vivo model of the disease. Here we describe the procedure for detection of the putative loci required for a septicemic pathogen to cause sepsis in humans by using TIS plus an ex vivo model of septicaemia: to grow the pathogen in fresh and inactivated human serum. We selected V. vulnificus because it is a highly invasive pathogen capable of spreading from an infection site to the bloodstream, causing sepsis and death in less than 24 h. To survive and proliferate in blood (or host serum), the pathogen requires mechanisms to overcome the innate immune defenses and metabolic limitations of this host niche. Initially, genes under-represented for insertions can be used to estimate the V. vulnificus essential gene set. Analysis of the relative abundance of insertion mutants in the library after exposure to serum would detect which genes are essential for the pathogen to overcome the diverse limitations imposed by serum.
