Inflammatory markers
   CRP, mg/L 7.0±0.6 9.8±1.0 0.004
   SAA, mg/L 82±8 111±13 0.284
   Fibrinogen, mg/dL 328±5 383±7 <0.001
   Lp-PLA2 mass, ng/mL 293±4 232±5 <0.001
   Lp-PLA2 activity, nmol/min/mL 173±2 141±3 <0.001
   PTX-3, ng/mL 2.33±0.15 1.87±0.23 <0.001

Data are expressed as mean ± SEM. Data for CRP, SAA, Lp-PLA2 mass, Lp-PLA2 activity and PTX-3 were logarithmically transformed to normalize the distribution of marker values before statistical analyses.
