1. Meet the diagnostic criteria for CKD stage 3-4 (15 ≤eGFR\<60 ml/(min\*1.73m2)) in the 2012 Kidney Disease Improving Global Outcomes (KDIGO) guideline.
2. Sarcopenia should be diagnosed According to the 2019 Asian Working Group for Sarcopenia (AWGS) diagnostic criteria for sarcopenia: ① Muscle strength: grip strength (\< 28 kg for males, \< 18 kg for females); ② Physical function: is assessed by walking speed over 6 m (\< 1.0 m/s) or five-repetition sit-to-stand test (5STS) (≥ 12 s) or recommended short physical performance battery (SPPB) (≤ 9); ③ Artificial skeletal muscle (ASM) of extremities: Bioelectrical impedance analyzer (BIA) (\< 7.0 kg/m2 for males and \< 5.7 kg/m2 for females). On the basis of meeting criteria ③, sarcopenia can be diagnosed if at least one of the first two items is met.
