a The relationship between the contributions of the six most discriminant bacterial genera to classification of microbiota as well as their relative abundance. b Accuracy of the random forest model established based on the six most discriminant bacterial genera for discriminating “healthy” (n = 39) and “unhealthy” (n = 59) microbiota. High indicates a probability above 0.50, and low indicates a probability below 0.50.
