Change in β-diversity measured by weighted UniFrac over time. Weighted UniFrac distance of each saliva microbiota sample compared to that individual's baseline sample at 4 h, 24 h, 7 days, and 14 days. A value of 0 would represent identical microbiota composition between samples, with a value of 1 representing maximal microbiota differences. Sample points are coloured by study group (probiotic—red; control—blue). Lines represent the median UniFrac distance of a given timepoint. Microbiota compositions change over time (regardless of study group), with a subset of individuals changing drastically at 7 and 14 days
