  1. The table is divided into four different outcome measures: “VAS at activity”, “VAS at rest”, “DASH” and “Grip strength”. 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
  2. *Indicates a significant p-value below 0.05
