Degrees of freedom for the log-rank χ2 test are one less than the number of categories of the variable.
Abbreviations: Hb, hemoglobin level; ANC, absolute neutrophil count; Plts, platelet count; K, 1,000.
Cytogenetic subgroups: Good, normal, del(5q) only, del(20q) only, −Y only; Intermediate, +8, single miscellaneous, double abnormalities; Poor, complex (ie, ≥3 anomalies) or chromosome 7 abnormalities.
P < .0001.
P value not statistically significant.
ρ Excluding patients with WBC counts > 12,000/μL.
P < .0005.
