Figure 1.

Hazard ratio of peripheral artery disease and critical limb ischaemia by cross-categories of high-sensitivity cardiac troponin T and N-terminal pro-brain natriuretic peptide. Models adjusted for covariates in Model 2 (age, gender, race, education, body mass index, total and high-density lipoprotein cholesterols, systolic blood pressure, antihypertensive drugs, smoking, diabetes, history of stroke/CHD/HF, and estimated glomerular filtration rate). Red indicates hazard ratio >5, orange 2.5–4.9, and yellow 1.25–2.49. CHD/HF: coronary heart disease/heart failure.
