SLEDAI-2K, systemic lupus erythematosus disease activity index 2000; LN, lupus nephritis; C3, complement 3; C4, complement 4; ESR, erythrocyte sedimentation rate; CRP, C-reactive protein; ANA, antinuclear antibodies; Anti-dsDNA Ab, anti-double-stranded DNA antibody; anti-Sm, anti-Sm antibody; Anti-RNP, anti ribonucleoprotein; Anti-SSA, anti-Ro/SSA antibody; anti-SSB, anti-La/SSB antibody. Numerical data presented as mean ± SD were analyzed using Student's t-test, Mann-Whitney U-test or Pearson's Chi-squared test. p <0.05 was taken as significant.
