Fig 6. A. Scatterplot representing the correlation analysis of NO level and fasting blood glucose (FBG) (n = 123). A significant positive correlation exists between the NO level and FPG level (r = 0.543, p < 0.0001) in all the groups except Type 2 diabetes with hypertension group. B. Scatterplot representing the correlation analysis of NO level and blood HbA1c level (n = 123). A significant positive correlation exists between the NO level and HbA1c level (r = 0.614, p < 0.0001) in all the groups except Type 2 diabetes with hypertension
