Adjusted analyses showed clinically meaningful and statistically significant decrements of physical and mental components of SF-12 (mean SF-12 summary scores in physical (-13.0 (-16.0 to -10.2)) and mental (-10.7 (-13.7 to -7.8)) components compared with people with mMRC=0) as chronic breathlessness severity increased, across five age groupings.en© 2017, BMJ Publishing Group Ltd and the British Thoracic SocietyDyspneaJournal article003007390610.1136/thoraxjnl-2016-2099080004176865000162-s2.0-85026853834346679Dal Grande, E.
