Table 3: The results of Stepwise Multiple Regression Analyses with Number of Sites with Periodontal Pocket Depths 5-6 mm, 7-8 mm and >8mm and Number of Sites with Bleeding at Probing at the re-evaluation as Dependent Variables. Independent Variables were Included in the Model if p<0.05

Dependent Variable Independent Variables Coefficient (B) S.D. p
Number of sites with periodontal pocket depths 5-6 mm at re-evaluation Number of sites with periodontal pocket depth 5-6 mm at baseline 0.40 0.06 <0.001
Smoking 2.5 0.99 0.01
Number of sites with periodontal pocket depths 7-8 mm at re-evaluation Number of sites with periodontal pocket depths 7-8 mm at baseline 0.46 0.10 <0.001
Smoking 3.9 1.1 0.001
Number of sites with periodontal pocket depths >8 mm at re-evaluation Number of sites with periodontal pocket depths >8 mm at baseline 0.32 0.02 <0.001
Number of sites with bleeding at probing at re-evaluation Number of sites with bleeding at probing at baseline 0.42 0.05 <0.001
