Patients who used a combination of oral hypoglycemic agents and insulin (aOR: 2.74, 95% CI: 1.09–6.86), did not take biguanide (aOR: 2.73, 95% CI: 1.16–6.43), reported hyperglycemia (aOR: 4.24, 95% CI: 1.53–11.81), and had comorbid diseases (aOR: 4.33, 95% CI: 1.08–17.34) increased the risk of having poor glycemic control. This evidence concerns the gene INS and Hyperglycemia.
