In order to compare posterior distributions of evolutionary rates for H7 HA1 on different NA subtype backgrounds, randomised pairing of sampled rate estimates on different NA backgrounds was performed (see Methods).
As may be observed from the means and 90% HPD intervals for d N / d S and the randomised pairing analysis for comparing distributions (Table 5), d N, d S and d N / d S did not differ substantially between HP and LP lineages, indicating that viral pathogenicity did not have a discernible effect on the average selective pressure experienced across H7 avian influenza HA1.
