Spss 25.0 program for windows

The IBM SPSS 25.0 program for Windows was used to analyze all of the results (IBM Inc., Armonk, NY, USA). Data for each group were represented as mean SD values, and differences between groups were assessed using one-way ANOVA (ANOVA, LSD). Significant changes were assessed at two levels of significance: p < 0.05 (significant) and p < 0.01 (extremely significant).

Statistical analysis was performed with the SPSS 25.0 program for Windows (IBM, USA). The variable of study was cell viability expressed as the % of cell viability. The normality of the data was analysed using the Shapiro–Wilk test. Student’s t-test was used to compare the concentration of MMC released by the BraidStent-SF-MMC at 3 and 6 h. A comparison between groups at 3 and 6 h was carried out using the Kruskal–Wallis test, and, in the case of statistical significance, a corresponding post hoc analysis was carried out using the Bonferroni test. The trend of % of cell viability over time at 3 and 6 h was analysed via the Wilcoxon signed-rank test. The confidence interval set at 95% (95% CI), and significance was determined with p < 0.05.
