Association (odds ratios and 95% CI) between type 2 diabetes and impaired kidney function.

Models	Impaired kidney function, eGFR (MDRD)		p-value	Goodness-of-fit p-value
	Cases (<60 ml/min/1.73 m2)	Controls (≥60 ml/min/1.73 m2)
Age-adjusted model	1.83 (1.45–2.29)	Ref (1.00)	<0.001	0.001
Multivariate model 1	1.70 (1.35–2.15)	Ref (1.00)	<0.001	0.004
Multivariate model 2	1.68 (1.33–2.12)	Ref (1.00)	<0.001	0.06
Multivariate model 3	1.50 (1.17–1.91)	Ref (1.00)	0.001	0.85

GFR was estimated using the MDRD equation.

Logistic regression models were used to estimate the odds ratios and 95% confidence intervals.

Goodness of model fit was conducted with Hosmer and Lemeshow goodness-of-fit test.

Multivariate model 1 = age, sex, and hypertension.

Multivariate model 2 = model 1 + body mass index.

Multivariate model 3 = model 2 + lipids (high-, low-density lipoprotein, triglyceride).
