Table 2 EuroQol-5D-3L (EQ-5D) dimension and index scores for adult idiopathic scoliosis cohort at 2-year follow-up compared to untreated scoliosis patients and population matched scores. Percentage of participants reporting level of problem per dimension where level 1 indicates no problem, level 2 indicates some problems, and level 3 indicates extreme problems. UK Index reported as mean (SD)

From: An observational study on surgically treated adult idiopathic scoliosis patients’ quality of life outcomes at 1- and 2-year follow-ups and comparison to controls
