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

Tandem repeats often confound large genome assemblies. A survey of tandemly arrayed repetitive sequences was carried out in whole genome sequences of the green alga Chlamydomonas reinhardtii, the moss Physcomitrella patens, the monocots rice and sorghum, and the dicots Arabidopsis thaliana, poplar, grapevine, and papaya, in order to test how these assemblies deal with this fraction of DNA. Our results suggest that plant genome assemblies preferentially include tandem repeats composed of shorter monomeric units (especially dinucleotide and 9-30-bp repeats), while higher repetitive units pose more difficulties to assemble. Nevertheless, notwithstanding that currently available sequencing technologies struggle with higher arrays of repeated DNA, major well-known repetitive elements including centromeric and telomeric repeats as well as high copy-number genes, were found to be reasonably well represented. A database including all tandem repeat sequences characterized here was created to benefit future comparative genomic analyses.
