Results of the analyses from the 2009–2010 National Health and Nutrition Examination Survey (NHANES) indicate that study participants with depression had higher CRP concentrations; that is, 47.01% of the study population with depression had CRP levels of ≥3.0 mg/L, and 29.06% had CRP levels of ≥5.0 mg/L [10]. The gene discussed is CRP; the disease is depressive disorder.
