The miRNAs relative expression levels (REL) are shown in arbitrary units. The data represent the mean (standard deviation). n indicates the number of patients with data available. ^Timing of blood sampling before or after surgery is indicated for stages I to III patients only. Mann–Whitney test. *Kruskal-Wallis test.
