Table 3 Logistic regression analysis in comparison with the reference group

	Low Cognitive Performance			Intermediate Cognitive Performance
Unadjusted Model	Odds Ratio	95% CI	p	Odds Ratio	95% CI	p

Standard Control Group (Hb_A1c 7–7.9%)	0.92	0.37–2.27	.812	1.37	0.55–3.42	.496
Adjusted Model	Odds Ratio	95% CI	p	Odds Ratio	95% CI	p
Poor Control Group (Hb_A1c > 8%)	3.17	1.17–8.60	.024*	3.23	1.27–8.20	.014*
Standard Control Group (Hb_A1c 7–7.9%)	1.15	0.37–3.62	.812	1.57	0.60–4.41	.391

High cognitive performance and intensive glycemic control were considered as the reference groups. Hb_A1c: Glycated Hemoglobin. Confounding variables: age, educational level. CI: Confidence Interval. *p ≤ 0.05
