(A) Results of Pearson's correlation analysis between serum creatinine (mg/dL) and age (years) in KNHANES group males (n = 456, r = −0. 522, P < 0.0001). (B) Results of Pearson's correlation analysis between serum creatinine (mg/dL) vs. age (years) in HC group males (n = 1,967, r = − 0.451, P < 0.0001). (C) Results of Pearson's correlation analysis between serum creatinine (mg/dL) and age (years) in KNHANES group females (n = 1,046, r = − 0.016, P = 0.5985). (D) Results of Pearson's correlation analysis between serum creatinine (mg/dL) and age (years) in HC group females (n = 2,619, r = − 0.011, P = 0.5618). Participants with sarcopenia are represented by orange symbols from (A) to (D) according to the cutoff values (<7.0 kg/m2 in men and <5.4 kg/m2 in women by DXA, and <7.0 kg/m2 in men and <5.7 kg/m2 in women by BIA) suggested by the AWGS 2019 [5]. Conversely, dark blue or yellow symbols represent negative (non-sarcopenic) subjects by the same cutoff.
