Table 5.
A: Hemodynamics characteristics. Continuous data are median (I quartile-III quartile), categorical data are absolute numbers (percentages). AVAi: Aortic Valve Area indexed. B: The table also reports results of the weighted Gamma models evaluating the association with valve type. Gamma models’ results are reported as Average Marginal Effect (AME) for ME vs. Intuity and Intuity vs. Inspiris, lower and upper bound of the 95% Confidence Interval, and p-value.
