Cardiovascular disease mortality associated with a low ABI (<0.9) and the metabolic syndrome after adjusting for other factors
| Low ABI | Metabolic syndrome | |
|---|---|---|
| Model 1: Age and sex | 2.19 (1.64–2.91) | 1.66 (1.26–2.18) |
| Model 2: Age, sex, and baseline cardiovascular disease | 1.85 (1.37–2.48) | 1.44 (1.08–1.90) |
| Model 3: Age, sex, baseline LDL cholesterol, smoking status, cardiovascular disease, and known and newly diagnosed diabetes | 1.56 (1.15–2.11) | 1.30 (0.97–1.76) |
| Model 4: Model 3 variables and metabolic syndrome (for low ABI as the independent variable) or low ABI (for metabolic syndrome as the independent variable) | 1.53 (1.13–2.07) | 1.26 (0.94–1.70) |
Data are adjusted hazard ratios (95% CI).
