Data are expressed as and number (percent). 1184 subjects measured albuminuria on urine dipstick. Abbreviation: DR: diabetic retinopathy; NPDR: nonproliferative diabetic retinopathy; PDR: proliferative diabetic retinopathy; BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; FPG: fasting plasma glucose; Hemoglobin A1c: HbA1c; eGFR: estimated glomerular filtration rate.
