Survival of AL patients in relation to various prognostic factors.

(A) Survival of patients based on PBPC count higher than 0.5 × 10⁶/L (lower curve) or less than or equal to 0.5 × 10⁶/L (upper curve; P = .003). (B) Survival of patients based on PBPC% higher than 1% (lower curve) or less than or equal to 1% (upper curve;P = .002). (C) Survival of patients based on serum β₂-microglobulin levels of 2.7 μg/mL or higher (lower curve) or less than 2.7 μg/mL (upper curve;P = .04). (D) Survival of patients based on presence (lower curve) or absence (upper curve) of dominant cardiac amyloid involvement (P = .03). (E) Survival of patients based on BMPC% higher than 10% (lower curve) or less than or equal to 10% (upper curve; P = .04).
