Buffalo hepcidin: characterization of cDNA and study of antimicrobial property.
Article in Veterinary research communications, 2011. 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
Hepcidin, a novel gene encoded, 25 residue, 2-3 KDa cysteine rich cationic peptide synthesized in liver cells play an important role in iron metabolism in addition to its antimicrobial activity. In this study hepcidin cDNA expressed on hepatocytes of Bubalus bubalis has been characterized and the antibacterial activity of buffalo hepcidin analog has been determined. The complete buffalo hepcidin sequence is of 324 bp and have an ORF of 249 nucleotides from 14 to 262. The sequence analysis at nucleotide level showed homology of 98.0% with cattle, 84.3% with pig, whereas with human, chimpanzee and gorilla 80.3%, 80.7% and 81.5% respectively. The percent identity of buffalo hepcidin cDNA to that of japanese macaque, dog, gibbon, mouse and norway rat are81.9%, 79.9%, 79.9%, 67.9% and 65.9% respectively. The hepcidin cDNA of buffalo and cattle showed a total difference of five nucleotides at position 15, 108, 225, 240 and 246 with no difference in deduced amino acid sequence. The base A(15), C(108), A(225), C(240), A(246) in cattle are replaced by G(15), G(108), G(225), T(240) and G(246) respectively in buffalo. The deduced amino acid sequence of buffalo preprohepcidin consists of 82 amino acids containing 10 strongly basic, 3 strongly acidic, 27 hydrophobic and 29 polar amino acids. The predicted molecular weight and isoelectric point (P(I)) for the peptide is 8883.67 Daltons and 8.804 respectively. Phylogenetic analysis both at nucleotide and amino acid level indicate that buffalo and cattle hepcidin sequences comprises one clad which is more closely related to pig compared to human. The chemically synthesized analog of buffalo hepcidin using Fmoc chemistry in solid phase had antibacterial activity.
