Survival analysis of patients with pNET. According to the classification of miRNAs in low or high based on the relative miRNA expression levels using receiver operating characteristic (ROC) calculation with Youden Index analysis the Kaplan–Meier survival analysis using the log–rank test was performed for (A) disease-free survival and (B) overall survival. “Protective miRNAs” include miRNA145-5p and miRNA183-5p, whereas “risk miRNAs” include miRNA132-3p, miRNA34a-5p, and miRNA449a. * p < 0.05, ** p < 0.01.
