Longitudinal multivariate Poisson analyses relating clinical attachment loss measures (using only interproximal sites) and pre-diabetes/diabetes progression stratified by baseline number of teeth

	Baseline number of teeth
	28 teeth (n=174)	24–27 teeth (n=406)	21–23 teeth (n=178)	4–20 teeth (n=183)
	IRR^a (95% CI)	IRR^a (95% CI)	IRR^a (95% CI)	IRR^a (95% CI)
Mean CAL	0.88 (0.57–1.35)	0.78 (0.52–0.99)^*	0.96 (0.76–1.21)	0.84 (0.58–1.22)
≥1 tooth with CAL ≥ 7 vs. none	0.92 (0.48–1.76)	0.69 (0.47–1.01)	0.85 (0.50–1.44)	0.80 (0.42–1.53)
Change in mean CAL (follow-up minus baseline)	1.32 (0.92–1.90)	1.35 (1.08–1.69)^*	1.27 (0.92–1.74)	1.34 (1.01–1.78)^*

Adjusted for age, gender, smoking status, family history of diabetes, education, waist circumference, alcohol consumption, and physical activity (METs)

Statistically significant at p ≤ 0.05
