Differential gene expression in duodenum of colored broiler chicken divergently selected for residual feed intake.
Article in Tropical animal health and production, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Feed constitutes about 70% of the total expenditure of poultry production. Maximizing the feed efficiency in juvenile period is essential to achieve low production cost. The efficiency of feed utilization was measured by RFI (residual feed intake) by calculating the difference between an individual animal's observed and its expected feed intake. The expression of genes influencing low and high RFI is required to know the basic molecular mechanism influencing feed efficiency. The present study aimed to estimate the RFI (0-5 week) in a population of indigenously developed colored broiler sire line chicken. The duodenum sample of high and low-RFI broiler chicken was used for microarray analysis. Duodenum exhibited 1030 differentially expressed genes after analysis. Out of total DEGs, 461 genes were downregulated and 569 were upregulated. The fold change of differentiallly expressed genes varies from - 162.6 to 1549.28. A subset of genes was validated by qRT-PCR and results were correlated well with microarray data. In functional annotation study of DEGs, 89 biological processes, 30 cellular components, and 29 molecular functions were identified. Study of the important differentially expressed genes and the related molecular pathways in the population may hold the potential for future breeding strategies for augmenting feed efficiency.
