Data is presented as n (%) or median (interquartile range). Early mobilization is given, if the first session was performed earlier than 72h after ICU admission. A p-value of < 0.05 was considered significant. SOMS Surgical Intensive Care Unit Optimal Mobilization Score (ranging from 0 to 4) [18–20]
