Fig. 6

miRNA expression differences between the three experimental groups. MA plots showing differentially expressed miRNAs between ADC and CTRL (a), SQCC and CTRL (b), ADC and SQCC (c), and NSCLC (average of ADC and SQCC) and CTRL (d). The blue lines stand for |log2 FC| = 1, the red dots represent the significantly different miRNAs with over twofold upregulation, the green dots represent the significantly different miRNAs with over twofold downregulation, and the black dots represent miRNAs with no significant difference. FDR < 0.05, P < 0.05, and |log2FC| ≥ 1 was considered as statistically significant
