  1. aThe results are expressed as mean (±s.d.) percentage value of nucleated marrow cells positive with the given marker.
  2. bCases pos. for CD123 PM nodules: indicates the number of cases positive and in the brackets, the percentage of cases positive for the presence of CD123-positive nodules of plasmacytoid monocytes.
  3. CD68/KP1: CMML, CMML-1, CMML-2 vs CML, P<0.001. CD34: CMML vs CMML-AT, P<0.001; CMML-1 vs CMML-2, P<0.05; CMML-1 vs CMML-AT, P<0.001; CML vs CMML-AT, P<0.01; aCML vs CMML-AT, P<0.05.
