Kaplan Meier overall and disease-free survival curves. (A) Overall survival in individuals with ARL who were core-antibody negative, those who were core-antibody positive with no evidence of reactivation, and those who were core-antibody positive with evidence of reactivation. The y-axis shows the probability of survival against time. No comparisons were significant (P > .9). (B) Disease-free survival in individuals with ARL who were core-antibody negative, those who were core-antibody positive with no evidence of reactivation, and those who were core-antibody positive with evidence of reactivation. No comparisons were significant (P > .5).
