Fig. 3

nMDS of the dissimilarity in microbial composition by ethnicity and symptoms of an upper respiratory tract infection using abundance-based (a) and binary-based (b) measures. Shown are iTaukei children, with (light blue) or without (dark blue) symptoms of an upper respiratory tract infection, and FID children, with (light brown) or without (dark brown) symptoms of an upper respiratory tract infection. The centre points represent the mean of each group and the lines represent distance from the mean for each sample. There was a significant difference between the four groups (p = 0.001), p value calculated using PERMANOVA. Stress values for figures are 0.158 (a) and 0.216 (b)
