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

Pack-TYPE transposons are a unique class of potentially mobile non-autonomous elements that can capture, merge and relocate fragments of chromosomal DNA. It has been postulated that their activity accelerates the evolution of host genes. However, this important presumption is based only on the sequences of currently inactive Pack-TYPE transposons and the acquisition of chromosomal DNA has not been recorded in real time. Analysing the DNA copy number variation in hypomethylated Arabidopsis lines, we have now for the first time witnessed the mobilization of novel Pack-TYPE elements related to the CACTA transposon family, over several plant generations. Remarkably, these elements can insert into genes as closely spaced direct repeats and they frequently undergo incomplete excisions, resulting in the deletion of one of the end sequences. These properties suggest a mechanism of efficient acquisition of genic DNA residing between neighbouring Pack-TYPE transposons and its subsequent mobilization. Our work documents crucial steps in the formation of in vivo novel Pack-TYPE transposons, and thus the possible mechanism of gene shuffling mediated by this type of mobile element.
