Pearson’s dendrograms (A) of the healthy control and untreated HIV/TB co-infected samples (n = 38); (B) after the exclusion of untreated HIV/TB co-infected samples with CD4 T-cell counts above 600 cells/mm3 (n = 36); (C) after the exclusion of five healthy controls (n = 31); (D) of the untreated HIV/TB co-infected samples after stratification based on CD4 T-cell count before sample exclusion (LCD: lower CD4 count, < 100 cells/mm3, HCD: higher CD4 count, > 100 cells/mm3, n = 9); and (E) the healthy control, untreated TB-positive and untreated HIV/TB co-infected samples after the exclusion of the seven samples (n = 53). The distance measure used in these dendrograms was Pearson’s and the clustering algorithm, Ward’s D
