Number (#) of procedures, mean (minimum −maximum) and median (Q1–Q3) values of the distributions of each exposure parameter (FT, Ka,r, PKA, NoE and NoI) for interventional cardiology procedures. P-value results from the Kruskal-Wallis test for the four procedures (CA, PCI, CA+PCI, and TAVI) were also presented.
