  • Standard error adjusted for 166 clusters in “study”. The odds ratio indicates whether the patients with that characteristic were more (>1) or less (<1) likely to respond to morphine, e.g. those with “more” age (older) were less (<1) likely to respond to morphine. BI: breathlessness intensity; COPD: chronic obstructive pulmonary disease; RLD: restrictive lung disease.
