Abstract:
Objective To evaluate the association between low ankle brachial index and risk of death. Methods Related cohort studies in the past 12 years were collected. Heterogeneity was analyzed with χ2 and I2. Pooled hazard ratio (HR) as the effect indicator and 95% confidence interval (CI) were used to estimate the association of low ankle brachial index and risk of death by fixed effect model ( inverse variance method). Results A total of 8 studies were included with sum sample size of 30 029. In heterogeneity analysis, χ2 was 5.46, I2 was 0. 0%, and P was 0. 604. Meta-analysis resulted in pooled HR of 1.69 (95%CI:1.55 - 1.84). Conclusion Low ankle brachial index is associated with increased risk of death.
