Table 4 Prevalence of possible and confirmed sarcopenia

From: Performance on sit-to-stand tests in relation to measures of functional fitness and sarcopenia diagnosis in community-dwelling older adults

  1. 30CST 30 s chair stands, 5TSTS  five time sit to stand, SMI skeletal mass index
  2. aChi-square test of homogeneity across all 4 groups
  3. bChi-square test of homogeneity comparing 30CST vs 5TSTS vs Grip strength
  4. cPhysical performance: Gait speed < 1.0 m/s or 5TSTS ≥ 12 s or Short Physical Performance Battery ≤ 9 [17]. Additional criteria of 30CST based on 20th percentile cut off was also used
