Home-based walking exercise in peripheral artery disease: 12-month follow-up of the GOALS randomized trial.

When analyses were repeated with adjustment for age, sex, race, and baseline physical activity level, the result for the outcome of 12‐month change in physical activity level measured by accelerometer became nearly statistically significant (mean 12‐month difference between the intervention and control groups=+114.1 activity units; 95% CI=−3.0 to +231.3; P =0.056) and the result for patient‐reported blocks walked in the past week was no longer statistically significant (mean 12‐month difference between the intervention and control groups=+12.6 blocks; 95% CI=−2.6 to +27.8; P =0.104).
