Fig. 1. Kaplan–Meier survival analysis for low-risk and high-risk HLA alleles to explore the risk of HIV-1 superinfection.

Fig. 1

Blue = individuals with the low-risk or high-risk allele; red = individuals without the low-risk or high-risk allele. (a) HLA-A*29; (b) HLA-B*35; (c) HLA-C*04; (d) HLA-C*16; (e) HLA-DRB1*07; (f) HLA-DRB1*08; (g) HLA-DRB1*11. P values were calculated using the log-rank test (Kaplan–Meier) and the partial-likelihood ratio test (Cox).
