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

Many Helicobacter pylori genetic studies would benefit from an ability to move DNA sequences easily between strains by transformation and homologous recombination, without needing to leave a conventional drug resistance determinant at the targeted locus. Presented here is a two-gene cassette that can be selected both (i) against, due to a Campylobacter jejuni rpsL gene (dominant streptomycin susceptibility in cells also carrying an rpsL-str(r) allele), and (ii) for, due to an erm gene (erythromycin resistance). This rpsL,erm cassette's utility was assessed by using it to replace four gene loci (mdaB, frxA, fur, and nikR) in four streptomycin-resistant [Str(r)] strain backgrounds (derivatives of 26695, SS1, X47, and G27MA). The resultant 16 strains (phenotypically erythromycin resistant [Erm(r)] and Str(s)) were each transformed with wild-type genomic DNAs, and Str(r) derivatives were selected. The desired Erm(s) Str(r) isolates were obtained at frequencies that ranged from 17 to 96% among Str(r) transformants, with the Erm(s) yield apparently depending on the strain background and genome location of the targeted locus. The ease of isolating unmarked transformants described here should be valuable for many H. pylori molecular genetic and evolutionary analyses.
