cell dose are confounded in that only young children are capable of receiving high cell doses. For example, Table G-4 reveals that only 2 percent of the high cell doses were transplanted into patients over 16 years of age. Since cell dose is expressed as TNC/kg, presumably there are few units that have sufficient numbers of cells to yield ratios above 5 × 107 TNC/kg for adults. Research into the viability of combining multiple units for a single transplant should be investigated. Finally, analysis of larger datasets with larger cell volumes and greater numbers of perfectly matched recipients is needed to confirm these preliminary results.
