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

High-throughput sequencing studies during the last decade have uncovered that bacterial genomes are very diverse and dynamic, resulting primarily from the frequent and promiscuous horizontal gene exchange that characterizes the bacterial domain of life. However, a robust understanding of the rates of genetic exchange for most bacterial species under natural conditions and the influence of the ecological settings on the rates remain elusive, severely limiting our view of the microbial world. Here, we analyzed the complete genomic sequences and expressed transcriptomes of several Shewanella baltica isolates recovered from different depths in the Baltic Sea and found that isolates from more similar depths had exchanged a larger fraction of their core and auxiliary genome, up to 20% of the total, compared with isolates from more different depths. The exchanged genes seem to be ecologically important and contribute to the successful adaptation of the isolates to the unique physicochemical conditions of the depth. Importantly, the latter genes were exchanged in very recent past, presumably as an effect of isolate's seasonal migration across the water column, and reflected sexual speciation within the same depth. Therefore, our findings reveal that genetic exchange in response to environmental settings may be surprisingly rapid, which has important broader impacts for understanding bacterial speciation and evolution and for modeling bacterial responses to human-induced environmental impacts.
