Table 1.
Median percentage of salivary bacteria. Data are grouped by phyla and sorted by median percent difference between 232 normal and 313 over-weight subjects. Probability values are computed from the nonparametric Mann-Whitney U test. Values significant at p<0.0013 are indicated with a “*” as an adjustment for multiple comparison for an overall p<0.05.
