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

The Muscovy duck (Cairina moschata) is an excellent lean-type poultry species characterized by large body weight, rapid growth, high lean meat yield, good liver production performance, and high feed conversion efficiency. It plays an important role in modern poultry industry. However, the quality of the currently available Muscovy duck genome remains limited. Here, we report the de novo sequencing and assembly of the Muscovy duck genome using PacBio and Hi-C technologies. The total length of the genome assembly was 1270.04 Mb, the contig N50 was 6.56 Mb, and the scaffold N50 was 77.04 Mb and it was composed of 39 chromosomes. BUSCO evaluation showed that 95.2% of conserved genes were completely assembled in the Muscovy duck genome, indicating high completeness of the assembly results. The genome annotation results showed that the proportion of repetitive sequences was 22.14%, 16,901 coding genes were predicted, and 93.4% of the genes were functionally annotated. Comparative genomic analysis revealed that expanded gene families were associated with immune-related pathways in Cairina moschata. Cairina moschata was closely related to Anas platyrhynchos and Aythya fuligula, both of which belong to the family Anatidae. These results provide valuable resources for poultry genomic breeding programs.
