In the linear mixed model analysis, the impact of some clinical characteristics was determined: age (p < 0.001), male sex (p = 0.008), and history of diabetes mellitus (p = 0.009) on CRP level, hypertension history (p = 0.017) on leucocytes level, male sex (p = 0.019), and prior MI (p = 0.008) on potassium level, age (p < 0.001), myocardial infarction history (p = 0.009), diabetes mellitus (p = 0.004), and history of stroke (p = 0.021) on hemoglobin level. The gene discussed is CRP; the disease is diabetes mellitus.
