Data are mean±SD, or n (%). P values were calculated using independent sample t-test or Chi-square test. SLE=Systemic lupus erythematosus; SD=Standard deviation; ESR=Erythrocyte sedimentation rate; CRP=C-reactive protein; RF=Rheumatoid factor; BUN=Blood urea nitrogen; PLT=Platelet; HDL=High-density lipoprotein; LDL=Low-density lipoprotein; TG=Triglyceride; FBS=Fasting blood sugar; C3=Complement component 3; C4=Complement component 4; dsDNA=Double-stranded DNA
