Shown are the 10th-50th-90th% (solid lines, •) of CD56⁺ NK cells (upper), CD3 (middle), and CD8 (lower) cells per microliter in children (left) and adults (right) after SBA⁻E⁻ unrelated BMT. The shaded gray area represents the 10th-90th% values of related SBA⁻E⁻ transplant recipients; the white line represents the 50th% of SBA⁻E⁻related transplant recipients. Patients were studied only once during each interval. The stippled area represents the 10th-90th% of 65 normal controls.
