miR-130b expression in different groups. (A) Differential expression levels of reference miR-16 (P>0.05). (B) ∆Cq values of miR-130b in different groups (P<0.05). The ∆Cq values denote the normalized Cq value by subtracting the Cq value of miR-16 from that of miR-130b. A lower ∆Cq value indicated a higher level of miR-130b expression. The Kruskal-Wallis H test was used to compare variables between three groups, and the Bonferroni method was used to correct for post hoc pairwise comparisons of significance levels. GC, gastric cancer; miR, microRNA; NC, healthy control; Pre, precancerous lesions.
