The secondary outcomes included HRQOL as measured by the self-administered standardized CRQ [12,13] and the Feeling Thermometer [14], dyspnea as measured by the modified Medical Research Council dyspnea scale and mortality. All of these outcomes have been validated in the languages required here (German, French and Italian) and have seen extensive use in clinical research and practice.…”
