Detection of decline in estimated glomerular filtration rate in patients with type 2 diabetes by cystatin C-based equations

Figure 1 Study flowchart. ADA: American Diabetes Association; BMI: Body mass index; G-6-PDH: Glucose-6-phosphate dehydrogenase; HbA1c: Glycated hemoglobin; HDL-C: High-density lipoprotein cholesterol; LDL-C: Low-density lipoprotein cholesterol; ACR: Albumin/creatinine ratio.

Figure 2 Distribution of study participants in estimated glomerular filtration rate values (mL/min/1. 73m²) according to cystatin C-based equations and the relationship between average serum cystatin C concentration (mg/L) and estimated glomerular filtration rate values. CKD-EPI: Chronic Kidney Disease Epidemiology Collaboration.

Figure 3 The percentage of estimated glomerular filtration rate decline in elderly diabetic patients. The estimated glomerular filtration rate (eGFR) was determined by the Chronic Kidney Disease Epidemiology Collaboration 2021 creatinine-cystatin C, then the percentage of patients who have declined eGFR (eGFR < 60 mL/min/1.73 m²) was calculated. eGFR: Estimated glomerular filtration rate.
