Waist circumference was included in model 4 (Table 3), in which it was observed that presence of insulin resistance was positively associated with MCP-1 (OR = 1.006, p = 0.024) and IL6 levels (OR = 1.361, p = 0.016), which were stronger than in the previous models 1 and 2. The gene discussed is IL6; the disease is Insulin resistance.
