MEF2A and coronary artery disorder: Results showed that the plasma level of MEF2A in the male CAD subgroup (0.95 ± 0.45 ng/ml) was significantly lower than that in the male control subgroup (1.42 ± 0.72 ng/ml) (z= -3.493, P < 0.001) (Table 2, Figure 6B), and the plasma level of MEF2A in the female CAD subgroup (0.83 ± 0.34 ng/ml) was also visibly lower than that in the female control subgroup (0.98 ± 0.42 ng/ml) (z = -1.797, P = 0.072) (Table 2, Figure 6C).
