2.3 Statistical analyses
We analyzed the data using BellCurve for Excel (version 3.20, Social
Survey Research Information Co., Ltd., Tokyo, Japan). To compare the
antithrombotic naïve patients and patients undergoing CAT to patients
with or without postoperative complications, we used the Mann‒Whitney U
test for continuous variables and Fisher’s exact test or chi-square test
for categorical variables. A p value < 0.05 was considered
statistically significant.
