Circulating miR-21-5p level has limited prognostic value in patients with hepatocellular carcinoma and is influenced by renal function

Figure 3 Overall survival analysis in relation to hsa-miR-21-5p level. A: All patients were divided into two groups: (1) Low: < 50^th percentile (n = 47) and (2) High: > 50^th percentile (n = 44), two patients exhibit exactly the median expression of serum hsa-miR-21-5p, that is why, the group division is not exactly symmetric; B: Overall survival analysis in patients with Barcelona Clinic Liver Cancer staging system A + B (divided into two groups: (1) Low: < 50^th percentile [n = 27] and (2) High: > 50^th percentile [n = 26]); C: Survival analysis in patients with Barcelona Clinic Liver Cancer staging system C + D (divided into two groups: (1) Low: < 50^th percentile [n = 20] and (2) High: > 50^th percentile [n = 18]). Nonparametric log-rank test was used for statistical analysis. MiR-21: Hsa-miR-21-5p.
