Table 3. Multivariate logistic regression analysis to predict the presence of retinopathy in 1,744 participants without previously diagnosed diabetes.

Independent variables	Beta‐coefficients	Standard errors	P‐values
Model 1
Age (10 years) Systolic blood pressure (10 mmHg) Fasting plasma glucose (1 mmol/L)	0.287	0.154	0.062
	0.130	0.068	0.055
	0.295	0.099	0.003
Model 2
Age (10 years) Systolic blood pressure (10 mmHg) HbA1c (1%)	0.271	0.154	0.078
	0.150	0.067	0.030
	0.412	0.163	0.011

Model 1 includes age, systolic blood pressure and fasting plasma glucose as independent variables. Model 2 includes age, systolic blood pressure and hemoglobin A1c (HbA_1c) as independent variables.
