^aA participant who had adequate HL referring to he/she was measured with a score of at least 25 scores points (80% of the total score)
^bCHU9D utility score was treated as continuous variable in the analysis
^cModel 1 was a univariate mixed-effects linear regression model with HL as the main effect and adjustment for class-level clustering effects controlled for only
^dModel 2 was a multivariate mixed-effects linear regression model, with adjustment for age, gender, residence area, school type, parental educational attainment and class-level clustering effects
^eMD referred to Mean Difference between groups, while SE was standard error
^fCI meant confidence interval
