Association between insulin resistance and BMI with FEV₁ in non‐hypoxemic COPD out‐patients

Objectives This study was conducted to determine the impact of insulin resistance using Homeostatic Model Assessment of Insulin Resistance (HOMA‐IR) score and BMI in non‐hypoxemic out‐patients with COPD on FEV 1 using linear and polynomial regressions and to determine their correlation. Methods COPD patients of both genders were included after informed consent. Fasting blood sugar and serum insulin were done to calculate HOMA‐IR, which were...
