Deregulation of Serum MicroRNA Expression Is Associated with Cigarette Smoking and Lung Cancer

Figure 6

Scatter plots of the correlation between serums let-7i-3p (a) and miR-154-5p (b) levels and the smoking index. The relative expression levels of the serum miRNAs were normalized to miR-16. The correlations between the serums let-7i-3p (, ) and miR-154-5p (, ) levels and the smoking index were analyzed using Pearson’s bivariate correlation.
