How well do EQ-5D cognition bolt-ons perform?
A new review brings together evidence from 28 bolt-ons across 100+ studies. Five-level versions often perform better; several show promising divergent & known-groups validity, but evidence gaps remain.

Do people value health gains for children more than adults?
In their study, De Silva et al. found strongest reactions were to children in pain; adolescents prioritised younger people, while parents often highlighted adults’ caregiving roles.
