The table is divided into the six different outcome measures: “VAS at activity”, “VAS at rest”, “DASH”, “Grip strength”, “DASH + VAS at rest” and “DASH + VAS at activity”. DASH = The disabilities of the arm, shoulder and hand. Grip strength is measured in kg. All models are adjusted for baseline measurements, prosthesis, age and gender. Predictors with a p value > 0.09 are not presented in the table
^*Indicates a significant p-value below 0.05
