Rank fitness landscapes of the haplotypes in each of two patients. A directed edge i → j exists between haplotypes i and j if the posterior fitness difference f_j − f_i can credibly be inferred to be >0, i.e., if, given the model, there is evidence for haplotype j being fitter than haplotype i. Both graphs possess the transitive property; i.e., if j is fitter than i (indicated by an edge i → j) and k is fitter than j, then k is also fitter than i and a directed path exists from i to k. Dark gray vertices possess credibly larger than average, light gray vertices possess average, and colorless vertices possess lower than average fitness φ = 1.
