Correlation between methods. Scatter plot demonstrates strong correlation between methods. R = 0.90 for method 1, R = 0.94 for method 2, R = 0.94 for method 3, R = 0.93 for method 4, and R = 0.95 for method 5, p < 0.001. Strongest correlations were seen if torsion > 7.5° as measured with method 0. The red circle illustrates a decreased correlation at lower torsion
