Distribution of the type I interferon in different organs of chicken digestive system.
Article in Central-European journal of immunology, 2014. 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
objectiveDistribution of the type I interferon in different organs of the chicken digestive system. MATERIAL AND
methodsIn order to obtain a certain length (274 bp) of a fragment, a pair of primers was designed according to the conserved nucleotide sequence of gallus IFNAR-1 (EU477527.1) fragment that was published by the GenBank. The fragment was cloned by pEASY-T1 and amplified by relative fluorescence quantitative PCR with SYBR Green I; according to the results, we made a standard curve. The experimental group took interferon orally, while the control group took equivalent physiological saline orally, then we used relative fluorescence quantitative PCR to detect the copies of the IFNAR-1 gene of the palate, tongue, esophagus, craw, glandular stomach, duodenum and rectum of the experimental group and control group. Copies of the IFNAR-1 gene of those organs were calculated by Ct value. Finally, all the chickens were infected with the Newcastle Disease Virus after 48 hours.
resultsThe results showed that the IFNAR-1 gene had the most expression in the esophagus. In the experiment of interferon antiviral activity detection, the chickens which took interferon orally were healthier than the other group.
conclusionsIt is confirmed that the interferon receptor did exist in the digestive organs. However, according to the physical and chemical properties of interferon, interferon is easily inactivated in the acid and alkali environment, by pepsin and trypsin, so the absorption site for interferon exists in organs above the craw, especially in the esophagus and tongue.
