Association between type 2 diabetes (T2DM) and changes in sedentary behavior patterns after completing 12 weeks of supervised exercise therapy (SET) for the treatment of symptomatic peripheral artery disease (PAD) (n = 44).

Each row represents an individual multiple linear regression model with the listed variable as the dependent variable and the listed B, SE, t, p, and 95% CI for the effect of T2DM adjusted for age, sex, BMI, ABI, current smoking, history of any peripheral revascularization procedure, number of exercise sessions completed, and minutes of valid wear time at baseline and 12 weeks.
Negative values represent a “desirable” response – decrease in that metric from baseline to follow-up.
