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

Strain typing methods that compare electrophoresis banding patterns are commonly used but are difficult to standardize and poorly portable. Multilocus sequence typing (MLST) is a sequence-based alternative, but it is not practical for large-scale epidemiological studies. In the present study, the usefulness of fimH single-nucleotide polymorphisms (SNPs) for Escherichia coli typing was explored. fimH SNPs were determined for 345 E. coli clinical isolates (including 3 reference strains) and compared to PCR-based ECOR (E. coli reference collection) phylogrouping. The fimH gene could be amplified for 316 (92%) of the 345 isolates. fimH SNP analysis found 46 distinct terminal groups in the nucleotide sequence-based phylogenetic tree (fimH types). A subset of the E. coli isolates (162 clinical isolates and the 3 reference strains) were compared by fimH type, PCR phylogroup, and MLST. These isolates fell into 27 fimH types and 18 MLST clonal complexes (CCs) that contained 2 to 28 isolates per complex. The combination of PCR phylogroup and fimH type corresponded to a single CC for 113 (68%) isolates and 2 or 3 CCs for the other 52 (32%) isolates. We propose that the combination of PCR phylogrouping and fimH SNP analysis may be a useful method to type a large collection of clinical E. coli isolates for epidemiologic studies.
