Table 2.

Salivary levels of IL-1β, IL-8, MIF, and MCP-1 expressed in pg/mL. Data are presented as the mean and standard deviation (sd) for the probiotic and placebo groups and p-values and confidence intervals (CI) are presented from comparison by groups performed on log10-transformed data via ANCOVA, with baseline values as covariate.
