Meaningful change in HRQoL at Week 56 for IWQOL‐Lite and SF‐36. Meaningful change was defined differently for the IWQOL‐Lite and the SF‐36 according to published algorithms. For the IWQOL‐Lite total score, the cut‐off for 'improvement' and 'deterioration' varied depending on baseline severity40. Cut‐off values are provided in Table S1. For the SF‐36 PCS, 'deterioration' was defined as a change from baseline ≤ −3.8; 'no change' between −3.8 and 3.8; and 'improvement' was a change from baseline ≥3.8. The corresponding values for the MCS were 'deterioration' as change from baseline ≤ −4.6; 'no change’, ‐4.6 and 4.6 and 'improvement' ≥4.6. CI, confidence interval; HRQoL, health‐related quality of life; IWQOL‐Lite, Impact of Weight on Quality of Life‐Lite; MCS, mental component summary; OR, odds ratio; PCS, physical component summary; SF‐36, Short‐Form 36.
