Early Onset Age Increased the Risk of Diabetic Retinopathy in Type 2 Diabetes Patients with Duration of 10–20 Years and HbA1C ≥7%: A Hospital-Based Case-Control Study

Table 3

The risk of DR and PDR according to onset age of T2D.

	DR		PDR
	OR (95% CI)		OR (95% CI)
Model 1	1.749 (1.338–2.287)	<0.001	1.452 (1.033–2.043)	0.032
Model 2	1.756 (1.342–2.298)	<0.001	1.476 (1.046–2.081)	0.027
Model 3	1.677 (1.273–2.207)	<0.001	1.403 (0.990–1.986)	0.057
Model 4	1.776 (1.326–2.380)	<0.001	1.605 (1.106–2.329)	0.013

Model 1 was unadjusted. Model 2 was adjusted for sex and BMI. Model 3 was adjusted for sex, BMI, HbA1c, and diabetic duration. Model 4 was adjusted for sex, BMI, HbA1c, diabetic duration, serum creatinine, TG, and hypertension. DR, diabetic retinopathy; PDR, proliferative diabetic retinopathy; T2D, type 2 diabetes; OR, odds ratio; BMI, body mass index; HbA1c, glycated hemoglobin; TG, triglycerides.
