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

Generation of a random transposon mutant library is advantageous in Leptospira as site-directed mutagenesis remains a challenge, especially in pathogenic species. This procedure is typically completed by transformation of Leptospira with a Himar1 containing plasmid via conjugation with Escherichia coli as a donor cell. Here we describe the methodology to generate random transposon mutants in the saprophyte Leptospira biflexa via conjugation of plasmid pSW29T-TKS2 harbored in E. coli β2163. Determination of transposon insertion site by semi-random nested PCR will also be described. A similar methodology may be employed to generate Tn mutants of pathogenic Leptospira species.
