Validation of differentially expressed miRNAs in AD patients compared to healthy controls according to (a–e) cigarette-smoking status, and (f–j) study group. Statistically significant differences were indicated as * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001, and ns = no statistical significance, according to Kruskal–Wallis test with Dunn’s post hoc test, followed by Mann–Whitney U test for pairwise comparisons. RQ, relative expression; AD, adenocarcinoma; CS, cigarette smoking; H, healthy controls. RQ values are presented in logarithm base 10 scale.
