At the univariable binary logistic regression model age (OR 1.07, 95% C.I. 1.04 – 1.09, p < 0.001), the number of chronic therapies at hospital admission (OR 1.24, 95% C.I. 1.13 – 1.35, p < 0.001), length of hospital stay (OR 1.07, 95% C.I. 1.04 – 1.1, p < 0.001), ICU stay (2.61, 95% C.I. 1.03 – 6.63, p = 0.04), NIV use during hospital stay (OR 2.09, 95% C.I. 1.18 – 3.70, p = 0.01), days of CRP above the upper normal limit (OR 1.08, 95% C.I. 1.04 – 1.11, p < 0.001) and muscle stiffness (OR 1.02, 95% C.I. 1.01 – 1.04, p = 0.003) resulted significant predictors of probable sarcopenia. Here, CRP is linked to sarcopenia.
