Figure 4.

Unrooted phylogenetic trees reconstructed from the complete NS5A region. Phylogenetic tree reconstructed using the maximum-likelihood (ML) method, a heuristic search with Nearest Neighbor Interchange (NNI) branch-swapping algorithm. A) HCV genotype 1b tree was based on the TVMef+G substitution model. B) HCV genotype 1a tree was based on the GTR+G substitution model. References are utilized in both trees. Patterns of response are represented by colors: sustained virological responders in red, non-responders in blue and end-of-treatment responders in green.
