The best fitting models and model-averaged results obtained by the GABranch analysis
| HLA allele | Best fitting model: ω rate classes (number of branches)1 | Model-averaged ω for HIV ancestral branch2 | Model-averaged Prob(dN>dS)3 for HIV ancestral branch |
| A*0201 | 1.14 (33), 0.62 (46) | 1.14 | 0.996 |
| A*6801 | 1.15 (42), 0.60 (31), 0.23(6) | 1.15 | 0.996 |
| B*2705 | 0.52 (79) | 0.52 | 0.06 |
1For each rate class, the value of ω is indicated followed by the number of branches (out of a total of 79) in brackets. 2The ω values are means over results from all the models. 3Prob (dN>dS) is the fraction of models that show support for dN>dS.
