Figure 5

Ordination of microbial composition together with physical and chemical parameters of AD samples. Redundancy analysis (RDA) was used to explore the main trends in the data. The canonical axes represent principal components. Sample (M1-M4) locations relative to each other indicate their similarity in the ordination space. Red squares indicate microbial groups in sequence data (a and b) and probes in microarray data (c and d), with the numbers indicating the microarray probes listed in the Additional file 2. Only the most abundant groups or strongest probe signals were included in the analysis. Blue arrows indicate the physical and chemical parameters used as constraining variables in the analysis (from Tables 1 and 2). The length and position of an arrow illustrates its significance on the canonical axes.
