As can be seen in Figure 3A the serum levels of MMP-9 were significantly higher in patients with diabetes (median: 0.0170 ng/ml; interquartile range, 0.0230 ng/ml) compared to healthy controls (median = 0.0055 ng/ml; interquartile range, 0.0145 ng/ml; p = 0.016). The gene discussed is MMP9; the disease is diabetes mellitus.
