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

In this study, we evaluated a recently developed multilocus variable-number tandem-repeat (VNTR) analysis (MLVA) method for the molecular typing of Mycoplasma pneumoniae. The method is based on GeneScan analysis of five VNTR loci throughout the genome which define a specific genotype based on the number of tandem repeats within each locus. A retrospective analysis of 154 M. pneumoniae clinical isolates collected over the last 50 years and a limited (n = 4) number of M. pneumoniae-positive primary specimens acquired by the CDC was performed using MLVA. Eighteen distinct VNTR types were identified, including two previously unidentified VNTR types. Isolates from several M. pneumoniae community outbreaks within the United States were also analyzed to examine clonality of a specific MLVA type. Observed in vitro variability of the Mpn1 VNTR locus prompted further analysis, which showed multiple insertions or deletions of tandem repeats within this locus for a number of specimens and isolates. To our knowledge, this is the first report showing variation within the Mpn1 locus, thus affecting precise and reliable classification using the current MLVA typing system. The superior discriminatory capability of MLVA provides a powerful tool for greater resolution of M. pneumoniae strains and could be useful during outbreaks and epidemiological investigations.
