Identification of an OTU signature associated with HIV-infected individuals. (a) PCA analysis of the sPLS-DA model fed with clr-transformed OTUs (left), and the resulting contribution of OTUs of component 1 (right). (b) OTU importance according to the random forest method. The Mean Gini Decrease of each OTU is plotted versus the delta of the CLR averages for each OTU (i.e., for each OTU, the ΔCLR was calculated subtracting the CLR mean of the HIV-infected group from the CLR mean of the control group).
