- Note: Predicted utility values are for the UK scoring algorithm of the Child Health Utility 9D based on adult values elicited using standard gamble.
- †Heteroskedasticity robust standard errors. *significant at 5%. For generalised linear model, binomial family and logit link were used.
- KS – the KIDSCREEN-10 index; KS_I1 – “fit and well”, KS_I2 – “energy”, KS_I3 – “sad”, KS_I4 – “lonely”, KS_I9 – “got on well at school”, KS_I10 – “been able to pay attention”.
