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 population structure of Legionella pneumophila was studied by using partial RNA polymerase gene (rpoB) and DotA gene (dotA) sequences. Trees inferred from rpoB sequences showed that two subspecies of L. pneumophila, Legionella pneumophila subsp. pneumophila and Legionella pneumophila subsp. fraseri, were clearly separated genetically. In both rpoB and dotA trees, 79 Korean isolates used in this study constituted six clonal populations, four of which (designated subgroups P-I to P-IV) were identified in L. pneumophila subsp. pneumophila and two of which (designated subgroups F-I and F-II) were identified in L. pneumophila subsp. fraseri. Although the relationships among subgroups were not identical, such subgrouping was congruent between the rpoB and dotA trees. Type strains of several serogroups did not belong to any subgroup, presumably because isolates similar to these strains were not present among our local sample of the population. There was evidence that horizontal gene transfer or recombination had occurred within L. pneumophila. Contrary to the phylogeny from rpoB and the taxonomic context, subgroups P-III and P-IV of L. pneumophila subsp. pneumophila proved to be closely related to those of L. pneumophila subsp. fraseri or showed a distinct clustering in the dotA tree. It can be inferred that dotA of subgroups P-III and P-IV has been transferred horizontally from other subspecies. The diverse distribution of serogroup 1 strains through the gene trees suggests that surface antigen-coding genes that determine serogroup can be exchanged. Thus, it can be inferred that genetic recombination has been important in the evolution of L. pneumophila.
