In univariate regression models, disability was significantly associated with BMI (OR: 4.60, 95% CI: 2.28–9.30), sex (OR: 2.25, 95% CI: 1.13–4.47), CDAI (OR: 15.69, 95% CI: 3.54–69.42), BMI (OR: 4.60, 95% CI: 2.28–9.30), sarcopenia (OR: 3.40, 95% CI: 1.59–7.72), and CRP (OR:1.31, 95% CI: 1.05–1.64) (Table 4). Here, CRP is linked to sarcopenia.
