Sarcopeniaweight was defined as skeletal muscle mass index (SMI, %) <2 standard deviations below the gender-specific mean for healthy young adults in the Korean population: SMI (%) <29.0 in men and <22.9 in women was considered as sarcopenia. In sensitivity analysis, sarcopeniaheight was defined as an appendicular skeletal mass/height2 ratio <7.0 in men and <5.7 in women. Model 1: crude model without any adjustment; Model 2=Model 1+age, sex; Model 3=Model 2+body mass index, follow-up duration, smoking, alcohol consumption, history of hypertension, exercise; Model 4=Model 3+estimated glomerular filtration rate, diabetes mellitus duration, glycosylated hemoglobin; Model 5=Model 4+use of statin, low-density lipoprotein cholesterol, triglyceride, high-density lipoprotein cholesterol, history of cardio-cerebrovascular disease (logistic regression analysis).
