Comparison of global χ2 values between different models. To detect hemodynamically significant stenosis, both kinetic energy (KE) and simulated fractional flow reserve (sFFR) with diameter stenosis (DS) had incremental value over DS alone (P < .05). KE had a higher χ2 value than the model that included DS and sFFR (P < .05). — Comparison of global χ² values between different models.
