Association between estimated glucose disposal rate and lower extremity arterial disease in type 2 diabetes: A nationwide cross‐sectional study from China

eGDR demonstrated a significant inverse L-shaped association with LEAD in patients with T2DM. These findings support the clinical utility of eGDR as a practical indicator of LEAD risk screening and management. Patients with lower eGDR may benefit from insulin-sensitising therapies, which could reduce both glucose levels and the risk of LEAD.
