Significant interethnic differencies in functional variants of PON1 and P2RY12 genes in Roma and Hungarian population samples.
Article in Molecular biology reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Antiplatelet therapy with clopidogrel is one of the most common therapies given to patients worldwide. However, the clinical efficacy and toxicity of clopidogrel is not constant in every patient due to interindividual variations. There are several factors that contribute to these interindividual differencies such as SNPs in genes of specific receptors and enzymes. PON1 (paraoxonase 1) plays an important role in the bioactivation of clopidogrel. Single nucleotide polymorphisms of this gene decrease the activity of paraoxonase enzyme and lead to an unefficient clopidogrel effect. P2RY12 (purinergic receptor P2Y, G-protein coupled, 12) gene is coding a receptor, which is situated on the surface of the platelets and plays a role in ADP-induced platelet aggregation. In this study we investigated 2 functional SNPs of PON1 gene (rs662 and rs854560) and 3 variants of the P2RY12 gene (rs2046934, rs6798347, rs6801273) in samples pooled from average Hungarian Roma and Hungarian population samples with PCR-RFLP method. For the PON1 variants we detected that the R allele frequency was significantly lower in the Roma group compared to the Hungarian population. (0.249 vs 0.318 p < 0.001). By contrast, the frequency of the M allele was significantly higher in Roma than in Hungarians (0.332 vs 0.290 p < 0.05). For the 3 P2RY12 variants we could find significant differencies only in rs2046934: the frequency of the CC genotype is 7 times higher in Hungarians than in Romas (1.4 vs 0.2 %, p < 0.05). The data presented here represent a unique genetic profile in Roma people that has not been reported for other populations.
