Notes: Data are reported as frequencies (percentages) for dichotomous or categorical variables and as mean (SE) for continuous variables. *p values adjusted for age and sex; †for trend p value. Poor muscle strength was defined according to sex-specific tertiles of muscle strength of knee flexor (kg) (M: 17.1, 21.5 kg; F: 11.3, 14.3 kg). Obesity is defined as a body mass index ≥30 kg/m2. VTE = venous thromboembolism; FICSIT = Frailty and Injuries: Cooperative Studies of Intervention Techniques.
