Table 4. Results of logistic regression for the dependent variable of mucositis.

Mucositis	OR	95% CI	P value
No. of implants (1 vs 2 implants)	2.27	0.76–6.81	0.1422
No. of implants (1 vs ≥3 implants)	4.53	1.36–15.05	0.0136
Presence of keratinized mucosa	0.82	0.3–2.29	0.7087
Smoking	0.54	0.18–1.61	0.2693

Variables showing a significant difference between patients with and without mucositis and peri-implantitis were included, along with smoking status and the presence of keratinized mucosa. Significant results are highlighted in bold (significance level P<0.05).

OR: odds ratio, CI: confidence interval.
