Pearson correlation analysis between the expression level of serum miR-15a-5p and the behavior of rats. A The level of miR-15a-5p was positively correlated with the escape latency of rats. B The level of miR-15a-5p was negatively correlated with the number of platform crossings. C The level of miR-15a-5p was negatively correlated with time in target quadrant. D The level of miR-15a-5p was positively correlated with total distance travelled. E The level of miR-15a-5p was negatively correlated with the rest time
