Figure 3

Microbial diversity analysis during first-line anti-TB treatment. (A) Depicts Alpha diversity for indices like Richness, Simpson and Shannon. (B) Depicts Beta diversity based on constrained ordination of the Bray–Curtis distances. Brown, orange and green represent months 0 (baseline), 2 and 5, respectively. The circular and triangular shapes in (B) denote HIV-negative and HIV-positive, respectively. Note this figure is based dataset C of Fig. 1 (n = 90 samples, 30 from each sampling point).
