How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

We studied associations between rs8193036 polymorphism of IL-17A gene (C737T) and plasma levels of IL-17A in patients with erysipelas and healthy subjects in a Kazakh population. The rs8193036 polymorphism was assessed in 95 patients with erysipelas and 383 control subjects. The IL-17A (rs8193036) polymorphism was studied by a real time polymerase chain reaction. Plasma levels of IL-17A were assessed in 90 patients with erysipelas and 90 healthy subjects by enzyme immunoassay. Categorical data were analyzed using Pearson's Chi tests and odds ratios (OR) with 95 % confidence intervals (CI). Continuous data were studied using Kruskal -Wallis and Mann-Whitney tests with Bonferroni correction. We found that T allele occurred more frequently (OR = 1.41; 95 % CI: 0.21-0.92) while allele C (OR = 0.71; 95 % CI: 0.51-0.99) and genotype CC (OR = 0.44; 95% CI: 0.21-0.92) occurred less frequently in cases than in controls. In erysipelas patients with CC genotype the level of IL-17A was significantly higher (p = 0.010) compared to the carriers of CT genotype. Also, the levels of IL-17A in patients with erysipelas was higher than among controls in groups with both CC and CT genotypes (p = 0.023 and p = 0.020, respectively). These data suggest that the rs8193036 polymorphism of IL-17A gene may play a role in the etiology of erysipelas, but other factors are also involved.
