SPSS 22.0 software was used for data analysis in this study. According to the normality of the data (using Kolmogorov–Smirnov test), parametric t-test or non-parametric Mann–Whitney U test was performed. Receiver operating characteristic (ROC) curve was used to evaluate the clinical diagnostic accuracy of abnormally expressed miR-218-5p in atherosclerosis. The value of Pearson correlation coefficient analysis is to evaluate the correlation between the level of miR-218-5p and the index. Data are presented as mean ± standard deviation [15 (link)]. P < 0.05 was defined as significantly different.
