Mean (±SD) periodontal profiles of periodontitis sites of interest. a Pl % (squares) and BOP % (circles), b PPD (squares) and PAL (circles), c Gingival crevicular fluid (GCF) volume (µL/30 s) of periodontitis-free (triangles) or periodontits (circles) sites, and d change in CADIA values over the study period. Dashed line placebo group; solid line mYJ group. Significant difference in CADIA value changes between periodontitis sites in placebo group compared with mYJ group at 12 months (*P = 0.025, repeated measures ANOVA with Dunnett’s post-test)
