PR, pulmonary rehabilitation; 6MW, 6-min walk distance; HR, heart rate.

P-value of PR. vs. Control was from Student's t-test between two groups.

P-value of the comparison between different times was from post-hoc test with Bonferroni correction for multiple comparisons [C5(2)]:

p <0.05/10 vs. discharge;

^†

p < 0.05/10 vs. 1 week;

^‡

p < 0.05/10 vs. 4 weeks.
