Table 1.

r2 values and time-delays for the cross-correlations between the 2D and the 3D torsion calculation method.

r2 (T2D) r2 (T*2D) Time delay (time lags) (T2D, T*2D)
Base-apex 0.99 ± 0.01 0.98 ± 0.02 0.0 ± 0.0

Base-mid 0.97 ± 0.02 0.96 ± 0.03 0.0 ± 0.0

Mid-apex 0.95 ± 0.02 0.93 ± 0.06 0.0 ± 0.0

Average 0.97 ± 0.02 0.96 ± 0.04 0.0 ± 0.0

One time-lag corresponds to 14 ms. A negative delay would indicate that the 3D method was delayed with respect to the 2D method. Values are mean ± SD.
