Study on genetic variations of PPARα gene and its effects on thermal tolerance in Chinese Holstein.
Article in Molecular biology reports, 2014. 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
Peroxisome proliferator-activated receptor alpha (PPARα) regulates responses to chemical or physical stress in part by altering expression of genes involved in proteome maintenance. In this research, polymerase chain reaction (PCR) technique was used to amplify 766 and 589 bp fragments of intron 3 and 7 of PPARα gene in Chinese Holstein (n = 771). Sequencing results showed that three novel single nucleotide polymorphisms (SNPs) were identified at position 44087 (G/A), 65550 (G/A), and 65676(G/A) in the PPARα gene. PCR-restriction fragment length polymorphism technology was used to genotype the three SNPs. Association analysis showed that cows with H1H8 (P < 0.05), H2H8 (P < 0.01), H5H7 (P < 0.05), H5H8 (P < 0.05), and H8H8 (P < 0.05) haplotype combinations had lower potassium content in erythrocytes than those with H2H6 haplotype combination. Cows with H1H8, and H8H8 haplotype combinations had lower decrease rate of milk yield than those with H2H6 and H6H8 haplotype combinations (P < 0.05). Cows with H2H8 and H8H8 haplotype combinations had lower rectal temperature than those with H5H8 and H7H7 haplotype combinations (P < 0.05). In conclusion, H8H8 haplotype combination may be advantageous for heat resistance traits in Chinese Holstein cattle.
