Description of the nested clade analysis. (A) shows the homogeneity test performed at level k (between clades C1 and C2). If it is not significant (B), a test will be performed at the following level (k+1), between all the sub-clades descending from clades C1 and C2, i.e between clades C1.1, C1.2, C2.1 and C2.2 (3 degree of freedom). If it is significant the analysis ends because an association is detected.
