Flow-chart of patient selection for the prediction analysis. One thousand twenty-five G-CSF mobilized allogeneic donors were identified in the EHR database. Donors with key demographical data (N = 186) missing or incomplete donor screening laboratory test data (N = 40) were removed. The remaining 799 donors were selected for the subsequent prediction analysis to identify donors with “poor/less-than-optimal” mobilization (Day 1 PB CD34 cell count <40/μL) or “good” mobilization (Day 1 PB CD34 cell count ≥40/μL).
