Study outcome data. (A) Normalized peripheral blood (PB) concentration of CD34⁺ cells ([CD34⁺]). (B) Normalized PB concentration of CD34⁺CD38^– cells ([CD34⁺CD38^–]). (C) Absolute PB [CD34⁺]. (D) Absolute PB [CD34⁺CD38^-]. n = 11 patients. Each donor is identified with the same color in all graphs. For (A) and (B), each dot represents an individual donor’s percentage change from their PB mean. A mixed model was used to estimate the quadratic trend in normalized values over time, assuming an autoregressive order 1 correlation structure. The three youngest donors have time point markers added to their lines. P values were obtained using paired t testing.
