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

We surveyed the diversity, structural organization, and patterns of evolution of DNA transposons in rotifers of the class Bdelloidea, a group of basal triploblast animals that appears to have evolved for millions of years without sexual reproduction. Representatives of five superfamilies were identified: ITm (IS630/Tc/mariner), hAT, piggyBac, helitron, and foldback. Except for mariners, no fully intact copies were found. Mariners, both intact and decayed, are present in high copy number, and those described here may be grouped in several closely related lineages. Comparisons across lineages show strong evidence of purifying selection, whereas there is little or no evidence of such selection within lineages. This pattern could have resulted from repeated horizontal transfers from an exogenous source, followed by limited intragenomic proliferation, or, less plausibly, from within-host formation of new lineages under host- or element-based selection for function, in either case followed by eventual inactivation and decay. Unexpectedly, the flanking sequences surrounding the majority of mariners are very similar, indicating either insertion specificity or proliferation as part of larger DNA segments. Members of all superfamilies are present near chromosome ends, associated with the apparently domesticated retroelement Athena, in large clusters composed of diverse DNA transposons, often inserted into each other, whereas the examined gene-rich regions are nearly transposon-free.
