Median percent of salivary bacteria most prominent in overweight individuals and identification by salivary levels of S. noxia. (A) Median percentage of salivary bacteria increasing with overweight relative to normal weight. Only changes greater than 2% are illustrated and sorted in the order of Normal:Overweight ratio. No reductions in median % of this magnitude were observed. (B). Categorization analysis based on the level of S. noxia greater than 1.05%. When S. noxia was considered as a diagnostic for overweight, it correctly identified 98.4% of individuals who were overweight (sensitivity) and 80.2% of individuals who were normal (specificity).
