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 family of leptospiral immunoglobulin-like (lig) genes comprises ligA, ligB and ligC. This study used PCR to demonstrate the presence of lig genes among serovars from a collection of leptospiral strains and clinical isolates. Whilst ligA and ligC appeared to be present in a limited number of pathogenic serovars, the ligB gene was distributed ubiquitously among all pathogenic strains. None of the lig genes were detected among intermediate or saprophytic Leptospira species. It was also shown that, similar to the previously characterized secY gene, a short specific PCR fragment of ligB could be used to correctly identify pathogenic Leptospira species. These findings demonstrate that ligB is widely present among pathogenic strains and may be useful for their reliable identification and classification.
