Relapse-free survival (RFS) and overall survival (OS) curves within normal/unknown cytogenetics subset based on bax/bcl-2 ratio levels.

(A) Kaplan-Meier plot comparing bax/bcl-2 ratio values with relapse-free survival. The difference between bax/bcl-2 ratio less than 0.3 group and bax/bcl-2 ratio more than 0.3 group was statistically significant (P = .03). (B) With regard to OS, the significant difference between less than 0.3 bax/bcl-2 ratio and more than 0.3 bax/bcl-2 ratio cases was maintained within the normal/unknown cytogenetics subset (P = .0016).
