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

The published genome sequence of Campylobacter jejuni strain NCTC 11168 was used to model an accurate and highly reproducible fluorescent amplified fragment length polymorphism (FAFLP) analysis. Predicted and experimentally observed amplified fragments (AFs) generated with the primer pair HindIII+A and HhaI+A were compared. All but one of the 61 predicted AFs were reproducibly detected, and no unpredicted fragments were amplified. This FAFLP analysis was used to genotype 74 C. jejuni strains belonging to the nine heat-stable (HS) serotypes most prevalent in human disease in England and Wales. The 74 C. jejuni strains exhibited 60 FAFLP profiles, and cluster analysis of them yielded a radial tree showing genetic relationships between and within 13 major clusters. Some clusters were related, and others were unrelated, to a single HS serotype. For example, all strains belonging to serotypes HS6 and HS19 grouped into corresponding single genotypic clusters, while strains of serotypes HS11 and HS18 each grouped into two genotypic clusters. Strains of HS50, the most prevalent serotype infecting humans, were found both in one large (multiserotype) cluster complex and dispersed throughout the tree. The strain genotypes within each FAFLP cluster were characterized by a particular combination of AFs, and among the cluster there were additional differential AFs. Identification of such AFs could act as a search tool to look for potential associations with disease or animal hosts, when applied to large number of human isolates. Genome-sequence based FAFLP, thus, has the potential to establish a genetic database for epidemiological investigations of Campylobacter.
