Table 1. Demographic and clinic characteristics of healthy controls and SLE patients studied.

Statistically significant differences between groups are shown in bold; p < 0.05. Normally distributed variables are displayed as mean ± standard deviation. Skewed variables are displayed as median (IQR). ACE = Angiotensin Converting Enzyme, HDL = High Density Lipoprotein, LDL = Low Density Lipoprotein, MPO = Myeloperoxidase, ESR = Erythrocyte Sedimentation Rate, SLEDAI = Systemic Lupus Erythematosus Disease Activity Index
