Sample distribution comparisons across community types. The labels located along the vertical axis represent five oral microbial community types (a and b belong to plaque samples, and c-e belong to saliva samples). Each bar represents the sample distribution percentage from different sources in each community type within the same niches. Sample number of each source assigned to each type placed to the right of the bar. Statistical significance was evaluated using Fisher’s test. P-values: **** < 0.0001, *** < 0.0001, ** < 0.01, and * < 0.05
