Spearman's correlation test was used. Data are expressed in correlation index and significance level (two digits represent r; three digits represent P). BMI: body mass index; HbA1c: glycated hemoglobin type-A1c; MMP-1: matrix metalloproteinase-1; TGL: triglycerides; TC: total cholesterol; TSH: thyroid stimulating hormone; PSA: prostate-specific antigen. Individuals with the GG, AG, and AA genotypes were, respectively, represented by 1, 2, and 3 in the analysis with all groups, whereas G homozygotes and carriers of the A-allele were represented by 1 and 2 in this order in the subsequent analysis. Significance threshold was set at P ≤ 0.05.
