  1. Legend:
  2. Type of study
  3. • O/AR: authors’ opinions, also based on an argumentative review
  4. • R(S): research based on survey
  5. • R: other than survey research
  6. • Rev: systematic or narrative literature review
  7. Is using QALY in the older population a main topic?
  8. • N: no
  9. • P: it is one of the main topics of the study, but not the only
  10. • Y: yes
  11. Type of problem discussed
  12. • Attrib.: QoL measured regardless of age, while different attributes/attribute measures are important for the older population
  13. • B-HA: no beyond-health QoL aspects taken into account
  14. • Instr.: problems with inadequacy of QoL measurement instrument
  15. • LE: lower LE causes lower QALY gains
  16. • QALY = QALY: equal value of one QALY regardless of age
  17. • QoL: poorer average health state causes lower QALY gain
