Kaplan-Meier curves of patients with low and high CD8 T-cell counts at diagnosis (< 180/mm³ or > 180/mm³, respectively). (A) All-cause survival. (B) Opportunistic infection (AIDS-defining illness)–related survival. The P value for the exact log rank test is also provided. Bottom lines represent the number of ICL patients still in follow-up at 12-month intervals. Vertical lines represent the time at which patients were censored: (A) at end of follow-up and (B) at end of follow-up or non-ICL death. In Figure 1A, one patient with high CD8 T-cell count died of a nonopportunistic infection after 96 months (at 114 months).
