Figure 5. NKp30 isoform profiles do not correlate with the loss of CD4⁺ T cells and are not a prognostic factor for time-to-AIDS or survival. For each of the three groups of patients as identified by the ratio cluster (green = Low C, blue = High B, violet = High C), Kaplan-Meier curves for time-to-loss of CD4⁺ T cells (< 200/mm³), time-to-first AIDS-defining event and survival are shown.
