			OR by sexc
	Adjusted OR (95% CI)a	P		Cases	Adjusted OR (95% CI)b	P
Number of teeth	0.980 (0.953-1.007)	0.148	Males	277	1.004 (0.969-1.040)	0.841

OR: odds ratio, CI: confidence interval.

^aAdjusted for sex, smoking habit, serum total cholesterol, fasting serum glucose, serum albumin, place of residence, marital status, and body mass index.

^bAdjusted for smoking habit, serum total cholesterol, fasting serum glucose, serum albumin, place of residence, marital status, and body mass index.

^cStratified by sex due to results of interaction tests, which indicated a statistically significant difference for risk related to tooth loss between males and females (P = 0.006) (see statistical analyses).
