Summary of exploratory endpoints. Error bars = 95% CI. ^a Analysis was performed using ANCOVA model with the following factors: For NBS: study product group and gender as factors and baseline NBS as covariate; for BI: study product group, gender and NBS strata as factors, and baseline BI score as covariate; for MGI: study product group, gender and NBS strata as factors, and baseline MGI score as covariate; for TPI (overall): study product group, gender and NBS strata as factors and baseline overall TPI score as covariate. Difference is first product minus second product (experimental minus negative control; experimental minus positive control; and positive control minus negative control), such that a negative difference favors the first product (experimental or positive control). ANCOVA, analysis of covariance; BI, Bleeding Index; CI, confidence interval; MGI, Modified Gingival Index; NBS, number of bleeding sites; TPI, Turesky Plaque Index
