Figure 2From: Appraising the performance of genotyping tools in the prediction of coreceptor tropism in HIV-1 subtype C viruses Ability of each approach at predicting CXCR4-usage in dual-tropic viral sequences. The percentage of dual-tropic sequences predicted as CCR5-using and CXCR4-using is shown with dark and light shaded areas of each bar corresponding to the percentage of sequences predicted as CCR5-using and CXCR4-using respectively.Back to article page
