The collected data were stored in a Microsoft Excel spreadsheet (Microsoft Inc., Redmond, WA, USA). Statistical analyses were conducted on an intention-to-treat basis, using SPSS software (SPSS, version 22 for Windows; SPSS Inc., Chicago, IL, USA) and R/R Studio software. The analyses were conducted using the Modified Intention-To-Treat population, which consisted of all the randomized participants who underwent at least one angioembolization [26 (link),27 (link)]. The Kolmogorov–Smirnov and Shapiro–Wilk tests were employed to validate the normality assumption of the data. Categorical data are shown as a frequency (% value) [28 (link)]. Continuous data are reported as previously described [29 (link),30 (link)]. The unpaired Student’s t-test [31 (link)], the chi-squared/Fisher’s exact tests, and the Wilcoxon rank-sum test [32 (link),33 (link)] were performed as appropriate. For the tests stated above, a p-value of 0.05 was considered statistically significant.
