Graphs showing the unadjusted association between participants’ health expectation gap (HEG), and World Health Organization Quality of Life Brief Version (WHOQOL-BREF) domain scores at the 6-mo follow-up. The HEG is defined as participants’ perceived health at 6 mo as measured using the EQ-5D visual analog scale (0-100 scale), minus their expected health (0-100 scale) at hospital discharge. When these two scores are identical, the HEG is 0. When expectations are exceeded, the HEG is positive. The WHOQOL-BREF comprises four domains, and each domain score is transformed to a 0 to 100 scale, with higher scores indicating better quality of life. Shaded areas depict 95% CIs. Spearman rank correlation coefficient is reported for each domain. Locally estimated scatterplot smoothing (LOESS) smoothers with α = .8 are displayed.
