Szukana fraza: [Abstrakt = "e comparisons were performed\). Results Treatment and treatment\-associated side effects in the Polish population of AAV were characterised in the first part of the analyses. The most frequently used medicaments in the remission induction treatment were glucocorticosteroids \(GCS\; 95.3%\), cyclophosphamide \(78.3%\) and rituximab \(9.3%\). Patients with GPA and MPA were administered steroid pulses more frequently than those with EGPA \(76.9% vs. 39.6%, p<0.01 and 78.4% vs. 39.6%, p<0.01, respectively\), as well as cyclophosphamide \(85.7% vs. 43.1%\; p<0.01 and 83.0% vs. 43,1% p<0.01, respectively\). On the other hand, methotrexate, azathioprine and GCS monotherapy were used more often in the EGPA group than GPA or MPA groups \(for methotrexate\: 15.7% vs. 5.3%, p<0.01 and 15.7% vs. 0.9%, p<0.01, respectively\; for azathioprine\: 13.7% vs. 3.4%, p<0.01 and 13.7% vs. 1.9%, p<0.01, respectively\; for GCS monotherapy\: 35.3% vs. 6.5%, p<0.01 and 35.3% vs. 14.2%, p<0.01, respectively\). Moreover, there was no case of rituximab nor plasmaphereses use during the remission induction phase in EGPA patients \(compared to 12.8% cases of GPA and 4.7% cases of MPA with rituximab use as well as 13.8% cases of GPA and 15.1% cases of MPA with plasmaphereses use\). Glucocorticosteroids, azathioprine and methotrexate were the most frequently administered drugs during maintenance therapy \(the propor"]
