Table 2 Results of binary and ordinal logistic regression analyses showing the relationship between the four subgroups and fall experience in older adults

From: Increased recurrent falls experience in older adults with coexisting of sarcopenia and knee osteoarthritis: a cross-sectional study

Variable No. (%) of participants OR (95% CI)† Proportional OR
(95% CI)†
No fall 1 fall 2 ≤ falls 1 ≤ fall 2 ≤ falls
Control (n = 90) 72 (80.0) 13 (14.4) 5 (5.6)  
Isolated sarcopenia (n = 12) 6 (50.0) 5 (41.7) 1 (8.3) 4.63 (1.28, 16.7) 2.19 (0.21, 22.6) 4.09 (1.18, 14.2)
Isolated knee OA (n = 164) 117 (71.3) 36 (22.0) 11 (6.7) 1.50 (0.79, 2.84) 1.03 (0.33, 3.24) 1.46 (0.77, 2.74)
Sarcopenia + knee OA (n = 25) 15 (60.0) 6 (24.0) 4 (16.0) 2.53 (0.91, 7.04) 4.17 (0.84, 20.6) 2.84 (1.05, 7.70)
  1. 95% CI, 95% confidence interval; OR, odds ratio
  2. Bold type indicates a statistically significant result
  3. † OR (95% CI) and proportional OR (95% CI) values of the four subgroups (control: reference) were calculated to indicate their predictive ability for fall experience (1 ≤ fall or 2 ≤ falls) while simultaneously including (1-step model) age, female sex, and body mass index. In the analysis for any falls experience (1 ≤ fall), recurrent falls (2 ≤ falls) were also included in a dependent variable
