The relative expression level of the circulating miRNAs under study in CAD. Fourteen miRNAs were analyzed: miR-21, miR-126, miR-133a, miR-135b, miR-140, miR-145, miR-146a, miR-155, miR-182, miR-196b, miR-200b, miR-205, miR-208a and miR-223. SNOR68 and RNU6B were used as an endogenous control. The values are represented as median (Q1 and Q3) using Whiskers and bars. All values were log-transformed with the control level sets at the Fold change equals 1. Mann–Whitney U test was used for comparison. *p-Values < 0.05 were considered statistically significant
