Fig. 3.

Box plots showing the richness (sobs) and diversity (invsimpson) of the microbiota in subjects treated with placebo (n = 48) or probiotic (n = 40) and colonised by the probiotic (n = 64) or not (n = 24).

Upper and lower edges of the boxes are the first and third quartiles; the line inside the box is the second quartile (median); individual dots are outliers.
