Tropism assignments based on HIV-1 env sequences derived from episomal cDNA and plasma viral RNA.

NA, no amplification of full-length or short env fragment; DM, dual/mixed; D, dual-tropic virus.*If amplification of the full-length env gene was not successful or if the phenotypic assay failed, secondary information on the virus genotype was derived by amplifying and sequencing a short fragment spanning the V3 region of env.aSeven more patients with concordant results between the two assays are presented in Table S1.
