For monocytes, none of the gating strategies produces significant differences between the Ki-67 proliferation index in non-clonal cytopenic patients and that in MDS patients (polygonal gating: p=0.95; rectangular gating: p=0.17; 40 FU threshold: p=0.48; 100 FU threshold: p=0.19). The gene discussed is MKI67; the disease is myelodysplastic syndrome.
