The expression levels of serum miR‐34c are increased in patients with aMCI. (a) MMSE and MoCA scores of the surveyed samples. (b) The relative expression levels of serum miR‐34c in patients with aMCI and normal controls. The 2^{−ΔΔ C t} method was used to determine the relative expression of serum miR‐34c levels for the surveyed samples, and the ΔC _t value of mi‐34c was transformed into log10^{−2 ‐ΔCt} as ordinate for statistical analyzed. (c) ROC curve of serum miR‐34c is established to distinguish aMCI from normal controls. (d, e) The correlations between serum miR‐34c levels and MMSE (c) or MoCA (d) scores by Spearman's correlation coefficient
