a
p-values from Welch’s t-tests to account for unequal variance between participants who achieved clinically significant outcomes and those who did not.
b
Fitness was measured using the 6-Minute Walk Test (6-MWT), which measures the number of meters that an individual can walk in 6 minutes. An increase of 50 meters or greater is considered clinically significant improved fitness.
