CD4 and AIDS: The first comparison revealed that the HLA-C∗07 allele group was overrepresented in patients with AIDS without CR (P=0.0163), and the second comparison showed that the HLA-C∗07 allele group was also overrepresented in patients with AIDS without CR (P=0.0298), indicating that the number of CD4 cells counts did not bias the results, and the HLA-C∗07 allele group did protect against CR development in patients with AIDS.
