OS according to sex differences in the various WHO subcategories of all patients (adult and children) with SM. Grey lines: male patients; black lines: female patients. The numbers at risk are given at the time points outlined on the X-axis. A: MIS: adults with mastocytosis in the skin who did not undergo a BM analysis; B: ISM: indolent systemic mastocytosis; C: SSM: smoldering systemic mastocytosis; D: ASM: aggressive systemic mastocytosis; E: MCL: mast cell leukemia; F: SM-AHN: systemic mastocytosis with an associated hematological neoplasm. As there were no events in patients with cutaneous mastocytosis only (OS 100%), the curves are not shown.
