Treatment with sc. PEG-IFN-β-1a predicts incidence of leukopenia and neutropenia. (a and b) Kaplan–Meier risk analysis for the occurrence of (a) leukopenia and (b) neutropenia under treatment with sc. PEG-IFN-β-1a (red) and sc. IFN-β-1a (blue). Log-rank test showed p = 0.003 for the occurrence of leukopenia and p = 0.01 for the occurrence of neutropenia. *p < 0.05. **p < 0.01.
