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
