Objectives To calculate estimated glucose disposal rate (eGDR) in newly diagnosed treatment naive patients with type 2 diabetes mellitus (T2DM) and correlate it with homeostatic model assessment of insulin resistance (HOMA-IR) and clinical/ biochemical parameters. Material and Methods eGDR was calculated using a formula based on waist circumference (WC) and body mass index (BMI) in 60 patients newly diagnosed with T2DM. HOMA-IR was calculated using fasting values of plasma glucose and insulin. S
