Figures & data
Figure 1 Classification of kidney injury. AKI was defined as a more than 50% rise in serum creatinine within 7 days, an increase of ≥ 0.3 mg/dL within 2 days, or oliguria for more than 4 hours. AKD is manifested by AKI or glomerular filtration rate (GFR) < 60 mL/min/1.73 m2, or a GFR decline of more than 35% from baseline value, or elevated serum creatinine levels (50% higher than baseline), or the presence of significant pathological injury and structural abnormalities, and the entire abnormal process lasts for less than 3 months. CKD refers to kidney structure and dysfunction caused by various reasons, or unexplained GFR decline (<60mL/min·1.73 m2); and the disease must be more than 3 months. Note: AKI, acute kidney injury; AKD, acute kidney disease; CKD, chronic kidney disease; GFR, glomerular filtration rate.
