Fig. 1From: Barriers to initiating SGLT2 inhibitors in diabetic kidney disease: a real-world studyRelationship between age and estimated glomerular filtration rate (eGFR) by albuminuria. Pearson coefficient between age and eGFR was r = -0.57 (p < 0.001). Blue dotted line represents correlation line. A1 ~ A3 denote albuminuria categories: A1, < 30 mg/g; A2, 30 ~ 300 mg/g; A3, > 300 mg/gBack to article page
