Cox model can separate NPC into high- and low- risk of distant metastasis groups. a-b Cox model built by using our signature (4 miRNAs: miR-142, miR-26a, miR-141 and let-7i) can separate NPC into high- and low- risk groups of distant metastasis; (c-d) Cox model built by using Liu’s signature (5 miRNAs: miR-93, miR-26a, miR-142, miR-29c and miR-30e) and performances; (e-f) Cox model built by using Bruce’s signature (4 miRNAs: miR-154, miR-449b, miR-140 and miR-34c) and performances; (g-h) Cox model built by using randomly generated signature (4 miRNAs: miR-653, miR-766, miR-1302 and miR-505) and performances
