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

Avena sterilis, the ancestral species of cultivated oats, is a valuable genetic resource for oat improvement. Here we generated a near-complete 10.99 Gb A. sterilis genome and a high-quality 10.89 Gb cultivated oat genome. Genome evolution analysis revealed the centromeres dynamic and structural variations landscape associated with domestication between wild and cultivated oats. Population genetic analysis of 117 wild and cultivated oat accessions worldwide detected many candidate genes associated with important agronomic traits for oat domestication and improvement. Remarkably, a large fragment duplication from chromosomes 4A to 4D harbouring many agronomically important genes was detected during oat domestication and was fixed in almost all cultivated oats from around the world. The genes in the duplication region from 4A showed significantly higher expression levels and lower methylation levels than the orthologous genes located on 4D in A. sterilis. This study provides valuable resources for evolutionary and functional genomics and genetic improvement of oat.
