Curves representing the prior (dotted black line) and posterior distributions (plain line) obtained for the selection coefficient s with scenarios P at HLA-DRB1 as well as MNSs and ABO loci. The modes and the 90% CI of the posterior distributions are given. For HLA-DRB1, s has also been estimated independently in North-Western Africa (in dashed grey) and South-Western Europe (in dashed blue), see text for details.
