Genetic diversity of mitochondrial DNA D-loop sequences in UAE native chickens.
Article in Poultry science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study was conducted to access the genetic diversity and phylogenetic relationship of United Arab Emirates (UAE) native chickens to support conservation of their genetic resources. A total of 161 native chickens were examined for genetic diversity and phylogenetic analysis using partial mitochondrial d-loop sequences (758 bp). The observed haplotype and nucleotide diversities were 0.670 and 0.0028 respectively, A total of 31 polymorphic site and 20 haplotypes were identified. These haplotypes were classified into four distinct haplogroups (A, B, C, and E), with E (95.6%) being the prominent maternal lineages of UAE native chickens. Phylogenetic analysis revealed that the haplogroup E of UAE native chickens clustered with the Indian Red Junglefowl (Gallus gallus murghi), suggesting a South Asian maternal origin. This lineage may have arrived in the country via an ancient trading network, especially through the maritime routes of the Indian Ocean. Other haplogroups were associated with East Asia and Southeast Asia origin. These results suggest that UAE native chickens have multiple maternal origins. The genetic diversity identified in this research will aid in the conservation and breeding of these chickens, focusing on economically advantageous traits.
