Table 4: Patients classified with moderate or high risk to physical disability due to sarcopenia according to the SMM index (Janssen et al. [27]) and as sarcopenic or non-sarcopenic according to the ASM index (Baumgartner et al. [26]) after 1 year and 2 years of supervised exercise intervention.

χ2: Chi-square. *: Significant difference compared to baseline (P ≤ 0.05). HIV-M: men, HIV-W: women. Cut-off points for detecting sarcopenia using the ASM index - 7.26 kg/m2 for men and 5.45 kg/m2 for women Cut-off points related to moderate and high risk of disability from sarcopenia using the SMM index - for men: 8.51-10.75 kg/m2 and ≤8.50 kg/m2, respectively; for women: 5.76-6.75 kg/m2 and ≤5.75 kg/m2, respectively.
