  1. The distributions of dN/dS ratios from groups of CT and control ORFs were compared with each other, and any difference assessed using the non-parametric Mann-Whitney rank sum test [43]. Ratios denoted by '∞' in Table 2 were omitted from this analysis. For comparison, differences in the distributions were also assessed for significance using a parametric Welch two sample t-test; see additional file 3.
