Figure 1

Comparative analysis of bacterial community at genus level of stool samples of children with ASD analysed by three different primer sets visualized by PCA. Analysis was performed at genus level using all detected (2731) bacterial genera. Set#1—515f/806r, set#2—27f/1492r, set#3—27f*/1495r. Unit variance scaling is applied to rows; SVD with imputation is used to calculate principal components. X and Y axis show principal component 1 and principal component 2 that explain 30.4% and 9.7% of the total variance, respectively. Prediction ellipses are such that with probability 0.95, a new observation from the same group will fall inside the ellipse. N = 29 data points.
