Kaplan-Meier analysis showing OS curves. According to FLIPI score (A), BMI positivity by PET (B), BMB result (C), separation by low and high stage based on BMB result (D), and separation by stage based on combined FDG and BMB result (E). Color bands indicate 95% CI. FLIPI score (>2), BMI positivity by PET, and high stage based on either BMB or combined results were associated with lower OS rates (P = .002, <.001, .02, and .03, respectively).
