N = available data for each variable; possible values = range for continuous variables and categories for dichotomized variables; descriptive statistics = mean value and standard deviation for continuous variables and absolute number and relative number for binary variables, age in years. BMI = body mass index (kg/m2); AIS = Abbreviated Injury Scale, interval between injury and hospitalization in days; BPI = Brief Pain Inventory; HADS-D = Hospital Anxiety and Depression Scale-depression subscale; HADS-A = Hospital Anxiety and Depression Scale-anxiety subscale; HFS = Hand Function Sort and SFS = Spinal Function Sort, normalized to 200 points; FCE = Functional Capacity Evaluation (kg).
