  1. Negative values indicate the mean log abundance was that amount less the lesion grade on the right; positive values indicate the mean log abundance was that amount greater than the lesion grade on the right. Values represent the difference in species abundance between lesion grades (e.g. T. denticola is 2.07 times less abundant in M0s compared to M1s).
