Figure 3. Kaplan−Meier survival curves for all-cause mortality by sarcopenia class/category with (A) for men and (B) for women. Normal skeletal muscle mass was defined as SMI ≥ 10.76 kg/m2 for men and ≥ 6.76 kg/m2 for women. Class I sarcopenia was defined as SMI 8.51-10.75 kg/m2 for men and 5.76-6.75 kg/m2 for women. Class II sarcopenia was defined as SMI ≤ 8.50 kg/m2 and ≤ 5.75 kg/m2 for men and women, respectively.
