IL6 and coronary artery disorder: Using chi-square test, we observed that the genotype distributions of IL-6-174G>C, -592G>C and -597G>A were in agreement with the HWE in both coronary artery disease patients (P values were 0.55, 0.79 and 0.71 for IL-6-174G>C, -592G>C and -597G>A, respectively) and control subjects (P values were 0.68, 0.89 and 0.51 for IL-6-174G>C, -592G>C and -597G>A, respectively).
