Characteristics of the complete mitochondrial genome of Douhua chicken (Gallus gallus) and phylogenetic considerations.
Article in Journal of animal science, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Douhua chicken is a unique local breed from Anhui Province, China. This study aimed to illustrate the Douhua chicken mitogenome and clarify its phylogenetic status by sequencing and annotating the complete mitochondrial genome using high-throughput sequencing and primer walking. Phylogenetic analysis through the Kimura 2-parameter model indicated the maternal origin of Douhua chicken. The results revealed that the mitochondrial genome is a closed circular molecule (16,785 bp) that consists of 13 protein-coding genes, 22 transfer RNA (tRNA) coding genes, two ribosomal RNA (rRNA) coding genes, and a control region. The base composition of the Douhua chicken mitogenome contains 30.3% A, 23.7% T, 32.5% C, and 13.5% G, and the haplotype and nucleotide diversity values are 0.829 (Hd) and 0.00441 (Pi), respectively. Furthermore, 10 haplotypes of D-loop sequences among 60 Douhua chickens were identified and distributed into four haplogroups (A, C, D, and E). Overall, the result of the present study indicates that Douhua chicken may have originated from Gallus gallus, and this process was influenced by Gallus gallus spadiceus, Gallus gallus murghi, and Gallus gallus bankiva. This study provides novel mitogenome data to support further phylogenetic and taxonomic studies on Douhua chicken. Additionally, the findings of this study will provide deeper insights for identifying the genetic relationships among populations and tracing maternal origins based on phylogenetic considerations for use in studies on the geographic conservation, utilization, and molecular genetics of poultry species.
