Filtering of differentially expressed miRNAs. (A) Data analysis pipeline to search for survival-correlated critically important miRNAs. (B) Volcano plot revealing a total of 46 miRNAs (red and green) that were differentially expressed between 312 NPC samples and 18 normal samples (cut-off criteria are fold change >2.5 and adjust P-value (FDR) <0.01). The red and green spots represent upregulated and downregulated miRNAs, respectively. miRNAs, microRNAs; NPC, nasopharyngeal carcinoma; DEGs, differentially expressed genes; ROC, receiver operating characteristic; WGCNA, weighted gene co-expression network analysis; PPI, protein-protein interaction; BPA; biological pathway; FDR, false discovery rate.
