Rarefaction curves (a) for V1/V2 and (b) for V3/V4, and alpha-diversity (c) for V1/V2 and (d) for V3/V4. The rarefaction curves were plotted for both sample groups separately. The alpha-diversity plot shows the distribution (boxplot) and individual sample values (circles), and whether the distributions were found significantly different between the sample groups (“NS” means not significant)
