Classification of the patients according to the European Medicine Agency algorithm. According to the EMA algorithm, all PR3-ANCA positive cases, three of six MPO-ANCA positive cases, and one double-positive case met the ACR criteria. The remaining three MPO-ANCA positive cases were diagnosed as GPA on the basis of the surrogate markers and positivity for ANCA without histological proof of granuloma or necrotizing vasculitis.
