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

backgroundThe relict gull (Larus relictus), was classified as vulnerable on the IUCN Red List and is a first-class national protected bird in China. Genomic resources for L. relictus are lacking, which limits the study of its evolution and its conservation.

resultsIn this study, based on the Illumina and PacBio sequencing platforms, we successfully assembled the genome of L. relictus, one of the few known reference genomes in genus Larus. The size of the final assembled genome was 1.21 Gb, with a contig N50 of 8.11 Mb. A total of 18,454 genes were predicted from the assembly results, with 16,967 (91.94%) of these genes annotated. The genome contained 92.52 Mb of repeat sequence, accounting for 7.63% of the assembly. A phylogenetic tree was constructed using 4902 single-copy orthologous genes, which showed L. relictus had closest relative of L. smithsonianus, with divergence time of 14.7 Mya estimated between of them. PSMC analyses indicated that L. relictus had been undergoing a long-term population decline during 0.01-0.1 Mya with a small effective population size fom 8800 to 2200 individuals.

conclusionsThis genome will be a valuable genomic resource for a range of genomic and conservation studies of L. relictus and will help to establish a foundation for further studies investigating whether the breeding population is a complex population. As the species is threatened by habitat loss and fragmentation, actions to protect L. relictus are suggested to alleviate the fragmentation of breeding populations.
