Data are presented as mean (SD) unless otherwise indicated
aShoulder pain at rest and at activity was assessed on a 100 mm visual analogue scale of 0 to 100, with 0 denoting no pain and 100 denoting extreme pain
bScoring system for evaluation of various shoulder disorders consisting of both objective (range of motion and strength) and subjective measurements (pain assessment, workload, and leisure time activities), summarised in a score between 0 and 100; higher score indicates better shoulder function
cBased on 12 questions with yes (1) or no (0) response options; maximum score is 12, indicating normal shoulder function; minimum score of 0 points indicates severely diminished shoulder function
dGeneric health related quality of life instrument comprising 15 dimensions; maximum score is 1 (full health), and minimum score is 0 (death)
eGeneric health related quality of life instrument to quantify the physical, functional, and psychological aspects of health-related quality of life. It consists of 36 questions in eight subscales that assess physical, functional, social, and psychological well-being. Score ranges from 0 to 100, where a higher score is associated with better health
