Patient-reported experiences and outcomes following two different approaches for non-surgical periodontal treatment: a randomized field study

Table 7 Multiple linear regression model^† to predict treatment outcome in terms of patients’ adherence to self-performed infection control i.e. proximal bleeding score at 6-months examination

Variables	B	95% CI	p value
Constant	8.62	− 5.96–23.20	0.246
Test group (ref: control group)	− 0.23	− 3.47–3.02	0.891
Current smoker (ref: non-smoker)	1.76	− 2.12–5.63	0.373
I have definitely been as involved as I wish in treatment (ref: else)	− 6.62	− 10.01 to − 3.22	< 0.001
GOHAI, mean score at baseline	0.10	− 0.09–0.06	0.591
VAS, pain/discomfort during treatment	− 0.01	− 0.26–0.45	0.727
Proximal bleeding score at baseline	0.22	0.16–0.28	< 0.001

^†Adjusted for background variables regarding, age, gender and education. n = 390. R² = 0.16
ANOVA gives the global p-value of the model and the significances of the individual covariates are presented in the table
