FIGURE 2.

(A) The expression levels of plasma microRNA 21‐5p (miR21‐5p) pre‐operation (Pre) and 7 d post‐operation (POD7) in non‐recurrence (n = 87) and recurrence / PD groups (n = 16). (B) The expression levels of plasma miR21‐5p at Pre and 1 mo post‐operation (POM1) in non‐recurrence (n = 87) and recurrence / PD groups (n = 16). (C) The expression levels of plasma miR21‐5p at Pre and 6 mo post‐operation (POM6) in non‐recurrence (n = 87) and recurrence/PD groups (n = 16). The Wilcoxon signed‐rank test was performed for comparisons between groups. *P < .05; **P < .01. (D) Postoperative changes in plasma miR21‐5p levels at POD7, POM1, and POM6 in the non‐recurrence (n = 87) and recurrence/PD groups (n = 16). The Mann‐Whitney U test was performed for comparisons between groups. *P < .05; **P < .01
