CD4 and AIDS: For each of the four outcomes considered (progression to CD4<200, AIDS 1987, AIDS 1992, and death), the antiviral contribution of an allele was negatively correlated with its HR, and this inverse correlation was borderline significant for the outcomes AIDS 1987 (p = 0.06), AIDS 1993 (p = 0.07), and death (p = 0.045).
