Figure 1From: Estimating the individualized HIV-1 genetic barrier to resistance using a nelfinavir fitness landscapeGenotypic correlates of genetic barrier. Impact of protease mutations and polymorphisms on the estimated genetic barrier to nelfinavir (NFV) resistance. For each mutation, the prevalence is indicated in the data set of protease inhibitor naive patients, which are all predicted as fully susceptible to NFV.Back to article page
