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

backgroudAquilaria sinensis (Lour.) Spreng is one of the important plant resources involved in the production of agarwood in China. The agarwood resin collected from wounded Aquilaria trees has been used in Asia for aromatic or medicinal purposes from ancient times, although the mechanism underlying the formation of agarwood still remains poorly understood owing to a lack of accurate and high-quality genetic information.

findingsWe report the genomic architecture of A. sinensis by using an integrated strategy combining Nanopore, Illumina, and Hi-C sequencing. The final genome was ∼726.5 Mb in size, which reached a high level of continuity and a contig N50 of 1.1 Mb. We combined Hi-C data with the genome assembly to generate chromosome-level scaffolds. Eight super-scaffolds corresponding to the 8 chromosomes were assembled to a final size of 716.6 Mb, with a scaffold N50 of 88.78 Mb using 1,862 contigs. BUSCO evaluation reveals that the genome completeness reached 95.27%. The repeat sequences accounted for 59.13%, and 29,203 protein-coding genes were annotated in the genome. According to phylogenetic analysis using single-copy orthologous genes, we found that A. sinensis is closely related to Gossypium hirsutum and Theobroma cacao from the Malvales order, and A. sinensis diverged from their common ancestor ∼53.18-84.37 million years ago.

conclusionsHere, we present the first chromosome-level genome assembly and gene annotation of A. sinensis. This study should contribute to valuable genetic resources for further research on the agarwood formation mechanism, genome-assisted improvement, and conservation biology of Aquilaria species.
