Figure 2. The volcano plot of differentially expressed miRNAs (DE-miRNAs) between ESCC patients with LNM and without LNM from the TCGA dataset. The purple dots and grey dots represent upregulated DEs and downregulated DEs with significance (adjusted p-value < 0.05 and |log2 (FC)| > 1), respectively. The black dots are those DEs without significance.
