Table 1: Average and standard deviation of the torsion axis location in the inferosuperior and mediolateral directions for the data without and with error (and different cut-off angles); value of comparison to data without error and combined value of location in and (based on Fisher’s combined probability); (number) in first column represents amount of samples included in analysis.
