 n/a not available. Number of branches: count of branches partitioned as foreground. LRT statistic: 2 times log likelihood difference of fixed versus free nested models.
 ^{a} Proportion of sites in category p0 where selection is purifying throughout the tree (0 < ω_{0} < 1).
 ^{b} Proportion of sites in category p1 where selection is neutral throughout the tree (ω_{1} = 1).
 ^{c} Proportion of sites in category p2 where selection is positive in foreground branches; sum of category 2a: purifying selection in background but positive selection in foreground (0 < ω_{0} < 1, ω_{2} > 1); and category 2b: neutral selection in background but positive selection in foreground (ω_{1} = 1, ω_{2} > 1
