Phylogenetic analysis of Clostridium botulinum type A by multi-locus sequence typing.
Article in Microbiology (Reading, England), 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 42 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
The genus Clostridium comprises a heterogeneous group of organisms for which the phylogeny and evolutionary relationships are poorly understood. The elucidation of these evolutionary relationships necessitates the use of experimental methods that can distinguish Clostridium lineages that are time and cost effective, and can be accurately and reproducibly employed in different laboratories. Multi-locus sequence typing (MLST) has been successfully used as a reproducible and discriminating system in the study of eukaryotic and prokaryotic evolutionary biology, and for strain typing of various bacteria. In this study, MLST was applied to evaluate the evolutionary lineages in the serotype A group of Clostridium botulinum. C. botulinum type A has recently been shown to produce multiple subtypes, suggesting that it is not monophyletic as previously reported, but comprises distinct lineages. For MLST analysis, we initially evaluated 14 housekeeping genes (gapdh, tuf, sod, oppB, hsp60, dnaE, aroE, pta, 23S rDNA, aceK, rpoB, 16S rDNA, mdh and recA) for amplification and sequence analysis. In the first phase of the analysis, 30 C. botulinum type A strains producing botulinum neurotoxin subtypes A1-A4 were examined. Results of this pilot study suggested that seven of the genes (mdh, aceK, rpoB, aroE, hsp60, oppB and recA) could be used for elucidation of evolutionary lineages and strain typing. These seven housekeeping genes were successfully applied for the elucidation of lineages for 73 C. botulinum type A strains, which resulted in 24 distinct sequence types. This strategy should be applicable to phylogenetic studies and typing of other C. botulinum serotypes and Clostridium species.
