Table 3: _Cont._Intra- and interobserver analysis of the hemodynamic parameters demonstrated a good reproducibility in the validation cohort for normalized flow displacement and flow jet angle (LoA \(\leq\)4.8% and \(\leq\)8.7\({}^{\circ}\) respectively, COV = 16-32%, r = 0.70-0.92, ICC = 0.80-0.94), an excellent reproducibility for vorticity norm (LoA \(\leq\)2779 s\({}^{-1}\cdot\)mL\({}^{-1}\), COV = 3-10%, r = 0.96-1.00, ICC = 0.96-1.00), and a very good reproducibility for absolute WSS\({}_{\rm mag}\), WSS\({}_{\rm ax}\), WSS\({}_{\rm cir}\), WSS\({}_{\rm angle}\), absolute helicity and volumes with increased absolute LNH (LoA \(\leq\)242 mPa, \(\leq\)244 mPa, \(\leq\)103 mPa, \(\leq\)8.9\({}^{\circ}\), \(\leq\)631 m\(\cdot\)s\({}^{-2}\cdot\)mL\({}^{-1}\) and \(\leq\)8.4 mL, respectively; COV = 3-26%, r = 0.86-1.00, ICC = 0.86-1.00). See Supplementary Materials Figures S1-S9 for the corresponding Bland-Altman plots. These plots demonstrated no striking dependency of the measured differences relative to the mean for the analyses and hemodynamic parameters.
