miRNA and DNA CN correlation analysis. Correlation analysis between DNA CN variations and miRNA expression. The red lines represent mature miRNA expression, normalized to Z30 small nucleolar RNA, expressed as 2-ΔCt, and converted between the interval values 0–1 (vertical axis on the right side). The spots represent the HMCL inferred DNA CNs (vertical axis on left side). Horizontal axis: HMCLs ordered according to increasing inferred CNs. The p value is indicated above each panel (Kendall's tau correlation test).
