Women confirming past but not present depression (n = 78) did not differ from women without a history of depression (previous or ongoing) (n = 77) regarding CRP levels (1.20 ± 1.13 versus 1.08 ± 1.13 mg/L); similar results were obtained also when analysing smokers and non-smokers separately. The gene discussed is CRP; the disease is major depressive disorder.
