Hazard ratios of total mortality for low (≤0.90) compared with normal (1.11-1.40) ankle brachial index in women in studies in the ABI collaboration.
(Hazard ratios are not adjusted for age or cardiovascular risk factors) (Area of each square is proportional to weight of the study in the meta-analysis).
(Total deaths/population for ≤ 0.90 group is 844/1901 and for 1.11 to 1.40 group is 1613/11,157).
