CRP: C-reactive protein; ESR: Erythrocyte sedimentation rate; HOMA-IR: Homeostasis model assessment of insulin resistance; sTWEAK: Serum tumor necrosis factor-like weak inducer of apoptosis; IL-6: Interleukin-6; Fetuin-A: Alpha 2-HS glycoprotein; * Spearman correlation. Values are shown as correlation coefficients (r); bold values indicate statistically significant values. Correlation is significant at the 0.05 level (2-tailed); **Correlation is significant at the 0.01 level (2-tailed).
