Analysis results for the myelokathexis (MK), cyclical (CN) and severe congenital (SCN) neutropenic patients of this study. The fraction f _a of apoptotic cells was determined as before. f _N , the fraction of circulating neutrophils relative to normal was based on the neutrophil count determined for each individual and a value of 4.4 × 10 ³  cells/mm ³ for normal individuals ( Dancey et al. 1976 ). The fraction f_T of the post‐mitotic marrow neutrophil precursor compartment (metamyelocytes and bands) was determined from actual bone marrow differentials on each patient and a normal value of 0.445 was determined from a weighted average of the figures of Dancey et al. (1976 ) (Table III, 43.2% of the total marrow neutrophilic cells were metamyelocytes and bands, n  = 13) and the control values of Chatta et al. (1996 ) (Table 2, the post‐mitotic pool constitutes 46.0% of total marrow neutrophils, n  = 13). The duration of the post‐mitotic compartment τ _m was taken to be 1.2 days from Hearn et al. (1998 ) for neutropenic patients. All else as in Table 1
