The graphs show serum levels of pentameric C-reactive protein (pCRP; A) and monomeric CRP (mCRP; B), as well as in mCRP/pCRP ratios (C) in systemic lupus erythematosus (SLE; n = 160) and ANCA-associated vasculitis (AAV; n = 30). Panel D illustrates levels of autoantibodies against complement protein 1q (anti-C1q) in SLE as well as in healthy controls (HC; n = 100). In addition, panel B includes a group of healthy controls (HC; n = 39; B). The dotted line represents CRP cut-off level applied for cardiovascular risk assessment in clinical routine (2.0 mg/L; A) (* = p ≤ 0.05, *** = p < 0.001)
