Fig. 1. Unsupervised clustering before antiretroviral therapy (ART).

Fig. 1

Gut bacterial profiles separated our participants in two main groups colored as gold and blue representing participants with low and high CD4% (Group 1 vs. Group 2), respectively. Orders of bacteria are separated into two main groups clustered by correlation. Overall, bacteria in the same cluster are positively correlated, whereas bacteria in different clusters are negatively correlated. Blue and red correspond to enrichment or depletion on proportions of bacteria, respectively.
