Kaplan-Meier analysis for the cumulative percentage of patients who remained hospitalized according to presence or absence of ARF with or without other single or multiple AOSD. (A) No ARF and no other single AOSD (hatched line), and ARF and no other single AOSD (solid line), P < 0.0001 by log rank test. (B) No ARF but presence of other single AOSD (hatched line), and ARF and no other single AOSD (solid line), P < 0.0001 by log rank test. (C) No ARF but presence of other single AOSD (hatched line), and ARF and presence of other single AOSD (solid line), P < 0.0001 by log rank test. (D) No ARF but presence of other multiple AOSD (hatched line), and ARF and presence of other multiple AOSD (solid line), P < 0.0001 by log rank test. Orfeas Liangos et al.
