  1. The reference category for intervention effect is the control group. The regression coefficients (β) indicate the average differences in clinical outcomes between the control and test group at 3-month follow-up
  2. BoP bleeding on probing, SoP suppuration on probing, PPD probing pocket depth, 95% CI 95% confidence interval
  3. aAdjusted for baseline values
  4. bAdjusted for baseline values, smoking, and mean bone loss at baseline
