A new methodology for differentiation and typing of closely related Salmonella enterica serovar Heidelberg isolates.
Article in Current microbiology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
This study describe the use of a combination of two recently proposed typing approaches, multiple amplification of prophage locus typing (MAPLT) and multiple-locus variable-number tandem-repeat analysis (MLVA) for subdividing within Salmonella enterica serovar Heidelberg (S. Heidelberg). The combined typing method was compared with pulsed-field gel electrophoresis (PFGE) by Simpson's index of diversity (DI). PFGE was shown to have a DI = 0.84 and was poor at differentiation of the predominant PT1 (Phage Type 1) phenotype. In comparison, the combined MAPLT/MLVA method comprising 3 MLVA and 9 MAPLT primer pairs provided a higher differentiating ability DI = 0.92. More importantly, the combined methodology was found to be superior in the differentiation of the predominant PT1 isolates. In conclusion, this study demonstrated the potential of the rapid and simple amalgamated MAPLT/MLVA approach in determining transmission of isolates of clonal phage type groups from various environmental sources to humans.
