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
