Plasma C4d, C4d/C4 ratio and sTCC levels are lower in remission in ANCA-associated vasculitis (AAV) patients than in active patients. C4d (a), C4 (b), C4d/C4 ratio (c) and sTCC (d) levels in active AAV patients at baseline in comparison to patients in remission after post-induction therapy. Data are presented as paired individual samples, and significance was calculated using Wilcoxon matched-pairs signed rank test. **p < 0.01
