Key result
Low ankle-brachial index (≤0.90) was independently associated with a significantly higher risk of all-cause mortality (RR 1.851) and cardiovascular mortality (RR 3.211) compared to normal index in Chinese patients with type 2 diabetes.

May aid risk stratification in Chinese T2DM; leaves open whether ABI-targeted interventions improve outcomes.

Yes

In Chinese patients with type 2 diabetes, a low ankle-brachial index is a strong independent predictor of both all-cause and cardiovascular mortality.
Li et al. (2007) conducted a cohort in Type 2 diabetes mellitus (n=1,647). Low ankle-brachial index (≤0.90) vs. Normal ankle-brachial index (0.91-1.40) was evaluated on All-cause mortality (RR 1.851, 95% CI 1.280-2.676, p=<0.001). Low ankle-brachial index (≤0.90) was independently associated with a significantly higher risk of all-cause mortality (RR 1.851) and cardiovascular mortality (RR 3.211) compared to normal index in Chinese patients with type 2 diabetes.
