Limitation
Firstly, the sample size of the present study is relatively small. Thus, the generalization of these conclusions needs to be further tested in larger cohorts. Secondly, we did not include TTI into statistical analysis because of the low TTI recording rate in the study. Finally, our data were collected with version 1.4.8a of the KODEX-EPD system. With the revolution of the system, more maneuvers will be clinically available to facilitate the CBA procedure in the near future.
