Factors associated with EQ-5D-5L utility index and Visual Analogue Scale scores in patients with coronary heart disease were analyzed by Tobit regression and Generalized linear model, respectively (n = 1247). The estimated effect and 95% confidence intervals were represented by black squares with the corresponding error bars. A two-sided P value 0.05 was considered statistically significant.
