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

Multiple theoretical studies have focused on the concerted evolution of the tandemly repeated rRNA genes of eukaryotes; however, these studies did not consider the transposable elements that interrupt the rRNA genes in many organisms. For example, in insects, R1 and R2 have been stable components of the rDNA locus for hundreds of millions of years, suggesting either that they have minimal effects on fitness or that they are unable to be eliminated. We constructed a simulation model of recombination and retrotransposition within the rDNA locus that addresses the population dynamics and fitness consequences associated with R1 and R2 insertions. The simulations suggest that even without R1 and R2 retrotransposition the frequent sister chromatid exchanges postulated from various empirical studies will, in combination with selection, generate rDNA loci that are much larger than those needed for transcription. These large loci enable the host to tolerate high levels of R1 and R2 insertions with little fitness consequences. Changes in retrotransposition rates are likely to be accommodated by adjustments in sister chromatid exchange (SCE) rate, rather than by direct selection on the number of uninserted rDNA units. These simulations suggest that the rDNA locus serves as an ideal niche for the long-term survival of transposable elements.
