Correlation of CD34⁺ cell content with neutrophil engraftment. Correlation of CD34⁺ total cell count and cell dose with time to neutrophil engraftment. (A) Regression of the time to engraftment on the total number of CD34⁺ cells (both on the natural logarithmic scale). The shaded interval is the pointwise 95% CI around the predicted log time. The regression line is log days to engraftment (5.70-0.50 log [10⁶ total cells]). (B) Regression of the time to engraftment on the number of CD34⁺ cells per patient actual body weight (both on the natural logarithmic scale). The shaded interval is the pointwise 95% CI around the predicted log time. The regression line is log days to engraftment (4.30-0.42 log [10⁵ cells per kg]).
