Multiple logistic regression analysis of severer periodontitis severity and higher leukocyte counts with carotid intima-media thickness ≥ 0.8 mm in military young adults.

	Crude model			Model 1			Model 2
	OR	95% CI	p value	OR	95% CI	p value	OR	95% CI	p value
Severer periodontitis (−)/higher leukocyte counts (−)	1.00			1.00			1.00
Severer periodontitis (−)/higher leukocyte counts ( +)	1.55	0.88–2.71	0.12	1.61	0.91–2.85	0.10	1.59	0.90–2.82	0.10
Severer periodontitis ( +)/higher leukocyte counts (−)	1.96	1.09–3.50	0.02	1.92	1.05–3.50	0.03	1.82	0.98–3.36	0.06
Severer periodontitis ( +)/higher leukocyte counts ( +)	7.83	2.89–21.19	< 0.001	7.33	2.62–20.50	< 0.001	6.45	2.21–18.84	0.001

Data are presented as odds ratios (OR) and 95% confidence intervals (CI) using multiple logistic regression analysis.

Multiple logistic regression model was additionally adjusted with age, sex, tooth brushing frequency, alcohol intake and tobacco smoking in Model 1; BMI was further adjusted in Model 2.

Severer periodontitis is defined as periodontitis stage II or stage III and higher leucocyte counts is defined as total leucocyte counts ≥ 7.6 10³/µL.
