CSF3 and anemia (phenotype): As described previously, the primary cause of the reduction was FN, and Table 3B shows the results of the analyses regarding its incidence, resulting in the same factors being identified (0.22; 0.07–0.65; P = 0.006 for baseline anemia, 0.05; 0.01–0.16; P < 0.0001 for prophylactic G-CSF use).
