Change in ankle-brachial index over time and mortality in diabetics with proteinuria.

Using time-to-event analysis, the risk for death was significantly higher in individuals with baseline ABI < 0.9 (hazards ratio (95% confidence interval): 2.23 (1.07, 4.65)); the higher risk for death in individuals with ABI > 1.3 or non-compressible arteries did not reach statistical significance (1.98 (0.97, 4.04)) ( Table 3 ) ( Figure 1 ).
