Spoligotype genotypes cluster analysis at baseline (diagram A) and follow up (diagram B). The figure shows the relationship between lineages and sublineages at baseline (diagram A) and follow-up (diagram B) to note clusters and measure of dissimilarity. Diagram (A) has 2 clusters, where the first cluster has lineage 1,3,1 and orphans and the second cluster is that of only lineage 4. The orphans are closely linked and similar to the lineage 1 EAI1_SOM and EAI5 clades. The second cluster of diagram (A) has only lineage 4 and simplicifolious in H37Rv sub lineage. The two clusters of diagram (A) have very small dissimilarities as the vertical heights are almost equal. The same observation on dissimilarity was made in diagram (B) which also two clusters. In the first cluster, lineage 2 has one clade compared to diagram (A) with two. The orphans are also linked to lineage 1 and 3 clades. The second cluster predominate sub lineage T1 has four clades which are close to X3 sub lineage. Comparing diagram (A) and (B), the measure of dissimilarity is higher in diagram (B)
