Multivariate analysis by GEE showed that the presence of insulin resistance was associated with increased MCP-1 (OR = 1.005, p = 0.007) and IL-6 levels (OR = 1.263, p = 0.026) and with reduced adiponectin levels (OR = 0.893, p = 0.033) after adjustment for skin color, age, waist circumference and glycated hemoglobin (Table 3, model 1). The gene discussed is IL6; the disease is Insulin resistance.
