Correlation of SLEDAI scores with plasma levels of mannose binding lectin (MBL), Anti-dsDNA, and complement components C3 and C4. SLEDAI scores correlated positively with plasma MBL (A) and anti-dsDNA levels (B). In contrast, plasma C3 (C) and C4 (D) levels negatively correlated with the SLEDAI. Dots represent individual samples. Correlation analysis was performed using the Spearman correlation coefficient. P < 0.05 was considered significant.
