Values are presented as Mean ± SD, and the units are pg/mL, except for CRP and SAP which were measured in ng/mL; IL = interleukin; TGFα = Transforming growth factor alpha; IFNg = Interferon gamma; MDC = Macrophage-derived chemokine; MCP-1 = Monocyte chemoattractant protein −1; TNFα = Tumor necrosis factor alpha; CRP = C-reactive protein; SAP = Serum amyloid P-component. Adjusted mean differences between groups obtained by linear regression model adjusting for number of chronic diseases, education and income. ^ Large effect size per Cohen convention.
