Values are means (SD) unless noted otherwise; p value represents the comparisons within the groups at baseline and follow-up assessments.
*if p<0.05 for between-group differences at the same time-point assessment.
†CV events at follow-up include the events present at baseline.
ASA, low-dose aspirin; BMI, body mass index; cIMT, carotid intima–media thickness; CRP, C reactive protein; CV, cardiovascular; ESR, erythrocyte sedimentation rate; HDL, high-density lipoprotein; LDL, low-density lipoprotein; NA, not available; TC, total cholesterol.
