Receiver operating characteristic curve to assess the optimal cut-off level of the
HPC count
The cut-off level of the HPC count for >2.0 × 106/kg of CD34+ cells in
a single apheresis was established as 21.0/µL, with a sensitivity of 0.78, specificity
of 0.63, and area under the curve of 0.74.
HPC, hematopoietic progenitor cell.
