Figure 3.NCR3 mRNA expression levels neither correlate with the loss of CD4⁺ T cells nor constitute a prognostic factor for time-to-AIDS or overall survival. For each of the three groups of patients as identified by the ΔΔCt cluster (light gray = High NKp30, dark gray = Inter NKp30, black = Low NKp30), Kaplan-Meier curves for time-to-loss of CD4⁺ T cells (< 200/mm³) time-to-first AIDS-defining event and survival are shown.
