Table 3. Adjusted odds ratios for thyroid cancer in diabetes duration model^*.

Variables	Interpretation	Thyroid cancer case number	OR	95% CI	P value
Diabetes duration	<1 year vs. Non-diabetes	1/794	0.071	(0.010, 0.507)	0.0084
	1–3 years vs. Non-diabetes	12/794	0.450	(0.250, 0.813)	0.0081
	3–5 years vs. Non-diabetes	11/794	0.374	(0.203, 0.689)	0.0016
	≥5 years vs. Non-diabetes	125/794	1.159	(0.914, 1.470)	0.2224

^*Other independent variables included in the model are the same as those shown in Table 2, except “diabetes status”. The OR (95% CI) for the other variables are not remarkably different from those shown in Table 2 and are not shown here. OR: odds ratio; CI: confidence interval.
