  1. In the regression equations, x is the absolute amount of misalignment (in degrees for rotational misalignment and in mm for translational misalignments) and y is the outcome measure as indicated in the top row in N or Nm respectively. A dash indicates that first and second degree polynomial fits did not meet the criterium of R2 > 0.7. All p-values were p < 0.01
