Predictors of Improved Walking after a Supervised Walking Exercise Program in Men and Women with Peripheral Artery Disease

Table 3

Four strongest univariate correlates of the change in ambulatory outcomes with baseline characteristics in symptomatic patients with peripheral artery disease.

Group	ΔCOT	ΔPWT
Women	Baseline COT	Baseline COT
	Baseline PWT	Angina
	Previous history of angina	Body mass index
	Lower extremity revascularization	Lower extremity revascularization
Men	Baseline COT	Obesity
	Baseline PWT	Abdominal obesity
	Total volume of exercise	Body mass index
	Baseline 6-MWD	Lower extremity revascularization

COT = claudication onset time, PWT = peak walking time, and 6-MWD = 6-minute walk distance.
Values are Pearson correlation coefficients.
