Table 5 Summary of correlations between cell doses demonstrating low correlation between total nucleated cell dose and CD8+ and CD34+ cell doses and moderate correlation with CD3+ and CD4+ cell doses

	CD3+ dose	CD4+ dose	CD8+ dose	CD34+ dose
CD4+ dose
R	0.91
R2	0.83
P	< 0.0001
CD8+ dose
R	0.81	0.55
R2	0.66	0.30
P	< 0.0001	< 0.0001
CD34+ dose
R	0.20	0.21	0.11
R2	0.04	0.04	0.01
P	0.0012	0.0009	NS
Total nucleated cell dose
R	0.71	0.64	0.56	0.38
R2	0.50	0.41	0.31	0.14
P	< 0.0001	< 0.0001	< 0.0001	< 0.0001

R: Pearson product moment correlation coefficient, R > 0.8 indicates highly correlated cell doses, R < 0.4 indicates low correlation between cell doses, R²: The square of the Pearson correlation, R²: 0.83 indicates 83% of the variance in one cell dose (e.g., CD3+) is determined by the other (e.g., CD4+); NS: Not significant (P > 0.05).
