MiR 26a as a stage-dependent biomarker and therapeutic regulator of inflammation in knee osteoarthritis

Figure 1 Comparison of serum between study groups. A: Comparison of serum miRNA-26a-2-3p fold change levels between study groups. Control (n = 50); grade 1 (n = 16); grade 2 (n = 22); and grade 3 (n = 12) (t test was insignificant at P > 0.05); B: Comparison of serum miRNA-26a5 fold change levels between study groups. Control (n = 50); grade 1 (n = 16); grade 2 (n = 22) and grade 3 (n = 12). t test was significant at ^aP ≤ 0.05, ^bP < 0.01 and ^cP < 0.001.
