MMP9 and hypertensive disorder: The serum concentration of MMP-9 in subjects diagnosed with MetS (P = 0.001) (Fig. 3a), hypertension (P = 0.001) (Fig. 3b), central obesity (P = 0.001) (Fig. 3c), high blood triglycerides (P = 0.018) (Fig. 3d), dyslipidemia or low HDL-C (P = 0.001) (Fig. 3e), and high fasting blood glucose (P = 0.012) (Fig. 3f) are significantly higher than subjects negatively diagnosed with those parameters.
