• Duration of oral antidiabetic drugs (r= -0.127, p-value=0.005)
• Age in years (r=-0.144. p-value=0.001)
• Duration of lipids drugs use (r = -0.097, p-value=0.042)
• Duration of antihypertensivedrugs (r = -0.137. p-value=0.005)
• Diastolic BP (mmHg) at baseline (r = 0.094. p-value = 0.036)
• Alkaline Phosphatase (IU/L) at baseline (r = 0.11. p-value=0.015)
Why The above variables show significant correlation with baseline HbAlc so that we can add them to regression model and why we can add them confounding effect control for (baseline HbA1c), which is the dependent variable, and (total cholesterol), which is the independent variable, should
