Reproducibility
The instrument was re-applied to 26 patients of the participants 14-21 days later. There were no significant differences in the first and second evaluation. QoL global, ICC = 0.80 (95 % CI 0.56 - 0.91); EF, ICC = 0.78 (95 % CI 0.51- 0.90); RF, ICC = 0.82 (95 % CI 0.59-0.92); GSS, ICC = 0.89 (95 % CI 0.76-0.95) ;(p <0.001, p <0.001, p <0.001, p <0.001).
