Model 1: Unadjusted.

Model 2: Adjusted for age and sex.

Model 3: Adjusted for age, sex, underlying diabetes mellitus, and congestive heart failure.

Model 4: Adjusted for age, sex, underlying diabetes mellitus and congestive heart failure, PD nurse advice after working hours, average duration during a training session, and total training time.
