Table 4. Estimated difference in total and domain CASI scores per 1 mmol/L higher fasting blood glucose from the linear relationship in diabetic men.

	Score	ΔCASI	95% CI	P-value
Model 1	Total CASI	−0.41	−0.70 to −0.17	0.038
	Short-term memory	−0.17	−0.24 to −0.05	0.022
Model 2	Total CASI	−0.38	−0.66 to −0.12	0.050
	Short-term memory	−0.16	−0.23 to −0.04	0.034

ΔCASI, difference in Cognitive Ability Screening Instrument; CI, confidence interval.

Model 1 was adjusted for age, total years of education and diabetic medication (yes/no).

Model 2 was adjusted for age, total years of education, diabetic medication (yes/no), body mass index, systolic blood pressure, hypertension medication (yes/no), lipid medication (yes/no), and smoking status (yes/no).

Other CASI domains had non-significant relationships with glucose (see eTable 2).
