^*Significance of p < 0.001 for before and after the 12-week Pulmonary Rehabilitation Program.

Anxiety and depression had a significant reduction of their levels (9.86 ± 6.55 vs. 7.53 ± 7.24^*; 11.25 ± 7.98 vs. 8.23 ± 6.81^*, respectively) when compared to before and after PRP. Another variable that had a significant improvement was the functional performance, which can be evaluated by the increase of distance traveled in the 6MWT (405.08 ± 99.41 vs. 459.92 ± 99.24^*).
