Associations between the NLR level quartiles and the prevalence of DR.

	NLR level quartiles				for tend	1SD increment of NLR
	Q 1 (≤1.38)	Q2 (>1.38, ≤1.77)	Q3 (>1.77, ≤2.30)	Q4 (>2.30)

Participants missing DR information () were excluded. Finally, 3266 participants were involved in the analyses. Data are expressed as odds ratios (95% CI). Binary logistic regression was used for analyzing the association between the NLR level and the prevalence of DR with and without adjusting the model. The associations of the NLR level with NPDR and PDR were analyzed by multinomial logistic regression with and without adjusting the model. ¹The model was adjusted for age, sex, education status, duration of diabetes, current smoking, BMI, HbA1c, dyslipidemia, and systolic blood pressure. DR: diabetic retinopathy; NPDR: nonproliferative diabetic retinopathy; PDR: proliferative diabetic retinopathy; NLR: neutrophil-to-lymphocyte ratio.
